This guide covers practical Aston Martin key fob tips, from quick battery replacements to improving security.

Stick around—your solution is just a scroll away!

Key Takeaways

  • Replace your Aston Martin key fob battery with a CR2032 type for smooth functioning. Always carry a spare battery or valet key to avoid emergencies.
  • Use the emergency key blade hidden in your key fob during signal issues or dead batteries. Learn how to unlock doors and start the car manually.
  • Protect against relay attacks by storing your fob in a signal-blocking pouch like those lined with Faraday fabric for better security.
  • Troubleshoot common problems, such as interference from phones, weak car batteries, or tinted windscreens that block signals affecting locking/unlocking functions.
  • For lost or damaged keys, contact an authorised Aston Martin dealership with proof of ownership and vehicle details. Replacing and programming can cost $800–$1,000 depending on model compatibility.

Key Features of an Aston Martin Key Fob

Key Features of an Aston Martin Key Fob

 

The Aston Martin key fob adds both style and function to your driving experience. Its standout design and advanced tech make it more than just a car key.

Passive Keyless Entry

Passive Keyless Entry lets you open your Aston Martin without touching the key fob. Approach your car with the crystal key in hand or pocket, and it unlocks like magic. It senses the transmitter's signal near the door handle.

This feature works with models like V8 Vantage (2005) and 2013 DB9. If it ever fails, interference from other devices might be to blame. Carry a spare plastic valet key for backup—it’s a lifesaver!

Crystal Key Design

The Aston Martin crystal key fob feels more like a piece of art than a car accessory. Crafted with glass and metal, it combines elegance with purpose. This “Emotional Control Unit” isn't just for show—it slides into the dashboard slot to start the vehicle, specifically models like the Aston Martin DBS V12 or Vanquish.

Its design sets it apart from plain plastic alternatives seen in brands like Volvo or Audi. The combination of weight and smooth finish creates an unmatched luxury feel. Owners often describe holding it as akin to carrying jewellery rather than just another car key.

 

"Owning an Aston is about details; even the key reminds you that you're driving something exceptional."

 

Remote Locking and Unlocking

The crystal key fob’s remote locking and unlocking feature works seamlessly. A simple press of the button locks or unlocks all doors, keeping your Aston Martin secure. Models like the Aston Martin Vantage (2005) and DB9 use this system for convenience.

LED door handle lights assist during night-time. Chumley-warner, an owner, appreciates these for easier visibility in dark areas. If parking near signal blockers or reflective surfaces like mirrors, interference may occur.

Holding the fob closer to your car can improve connection reliability.

Tips for Using Your Aston Martin Key Fob

Tips for Using Your Aston Martin Key Fob

 

Mastering your Aston Martin key fob makes life simpler and your car safer. Use it smartly to lock, start, or even handle emergencies with ease.

How to Start the Car

Starting your Aston Martin is simple but feels special. The key fob plays an important role, so let’s break it down step-by-step.

  1. Insert the Key Fob
    Slide the crystal key fob into the slot on the dashboard. Push it gently until it clicks into place. This activates the car's system.
  2. Press the Start Button
    Once the key is inserted, press the “Start/Stop” button located above it. Hold it briefly to start up your luxury engine.
  3. Foot on Brake or Clutch
    Keep your foot pressed firmly on the brake if driving an automatic, or clutch for manual models—like some variants of Aston Martin DB9 or Vanquish.
  4. Check Dashboard Lights
    Watch for warning lights on your display screen. If everything looks normal, you're good to go.
  5. Address Any Errors
    If an error occurred—like a dead battery in your fob—you may need a spare fob or emergency assistance. Keep a CR2032 battery handy for quick replacements.
  6. Deactivate Immobiliser System
    The remote keyless system works with Aston Martin's immobiliser safeguard. Make sure there's no interference from nearby electronics like phones or chargers.
  7. Listen for Engine Sound
    A smooth rumble confirms success! Models like Rapide and Virage offer both power and elegance as their motors roar to life.
  8. Use Emergency Key Blade (If Needed)
    Should any issue arise where your remote won’t work, open manually using the hidden emergency blade stored inside most Aston Martin keys.

Following these steps makes starting easy, even for first-time drivers of such exquisite vehicles!

How to Lock and Unlock the Doors

Locking and unlocking your Aston Martin doors isn’t complicated, but knowing a few tricks helps. The key fob does the heavy lifting for you, combining style and function. With just a press of a button, you can secure your vehicle or grant access effortlessly, ensuring convenience and elegance go hand in hand. However, if you ever encounter issues with the system, such as a malfunctioning mechanism, an Aston Martin door lock replacement might be necessary to restore seamless operation. Staying proactive with maintenance can help you avoid disruptions and keep your car in peak condition.

  • Press the Lock Button
    Tap the lock button on your Aston Martin key fob. The car will flash its indicator lights to confirm it’s locked. This works within a short range, up to about five metres.
  • Unlock with the Unlock Button
    Hit the unlock button once. This opens the driver’s door only for added safety. A second press unlocks all doors.
  • Use Passive Keyless Entry
    If you’re carrying the key fob, simply touch the door handle lightly. The car senses your key nearby and unlocks automatically.
  • LED Door Handle Lights
    At night, LED lights around the handles guide you. It’s especially appreciated by users like Chumley-warner for its practicality during dark hours.
  • Emergency Key Blade Usage
    Pull out the hidden metal key blade from your fob if needed. Insert this into a concealed slot near the handle to lock or unlock manually. Use this feature during rare battery failures.

Each option suits different situations—whether securing privacy or easing nighttime access, maintaining control is seamless with these steps!

Using the Emergency Key Blade

Sometimes, your Aston Martin key fob may not work. A dead battery or signal issue might leave you needing the emergency key blade. Here’s how to use it:

  1. Locate the Key Blade
    Check the back or side of your fob. There’s usually a small latch or button to release the hidden emergency blade.
  2. Remove the Emergency Blade
    Press and slide the latch while gently pulling out the metal key. It’s often tucked neatly inside a slot within the fob's housing.
  3. Access the Door Lock
    Inspect your car door handle for a hidden lock cylinder. These are often concealed behind a small plastic cover.
  4. Pop Open the Cover
     

    Use gentle pressure with your fingernail or tool to lift and remove this cover, exposing the keyhole underneath.

  5. Unlock with Ease
    Insert the emergency key into this exposed slot and turn it to unlock your door manually.
  6. Start Your Car (If Needed)
    Some Aston Martin models allow starting without a working fob if you insert this blade into a designated slot near the ignition area, like in older Ford systems.
  7. Reinsert Blade After Use
    Slide it back into its place in the fob carefully to avoid losing it.
  8. Replace Fob Batteries Soon
    A flat battery can leave you stranded again, so swap for new ones right away using quality replacements from trusted brands like Buick or Volvo spare keys' recommendations.

This simple tool can be a lifesaver in tight situations!

Troubleshooting Common Key Fob Issues

Troubleshooting Common Key Fob Issues

 

Got a dead key fob or it’s acting stubborn? Learn simple fixes to keep your Aston Martin running smoothly.

Replacing a Dead Battery

A dead Aston Martin key fob battery can stop your car from unlocking or starting. Fixing it is simple and doesn't need much time.

  1. Check for a Dead Battery

    Look out for signs like unresponsive locking or unlocking. If the key fob shows no lights or stops working, the battery is likely drained.

  2. Gather Necessary Tools

    Use a small flathead screwdriver to open the fob. Have a new button-style battery (usually CR2032) on hand.

  3. Open the Key Fob

    Locate the seam where the two halves meet. Gently insert the screwdriver and twist to pop it open. Be careful not to damage the crystal design.

  4. Remove the Old Battery

    Carefully take out the old battery using your fingers or a plastic tool if it's stuck. Avoid using metal tools that may scratch parts inside.

  5. Insert New Battery

    Place a fresh CR2032 battery into the slot with its positive (+) side facing upward. Ensure it sits snugly in place.

  6. Reassemble the Key Fob

    Align both halves of the fob and push them back together until you hear them snap in place.

  7. Test Your Key Fob

    Press any button to see if it lights up or starts responding again. Check its range near your Aston Martin Rapide, Vanquish, or DB9.

  8. Dispose of Old Battery Safely

    Take used batteries to a recycling centre, as they can harm the environment if thrown away carelessly.

Reprogramming the Key Fob

Reprogramming an Aston Martin key fob might sound tricky, but it can be done with the right steps. If your fob stops working, reprogramming is often the fix. Here's how:

  1. Start with the car ignition

    Insert your key into the ignition slot. Do not turn it yet. This step connects the key to the car's system.

  2. Turn on electrical systems

    Turn the ignition to position one (ACC mode). The lights on your dashboard should come on but don’t start the engine.

  3. Press and hold buttons

    On your key fob, press and hold both the "lock" and "unlock" buttons at the same time for 10-15 seconds. This sends a signal to sync with your car.

  4. Wait for confirmation
    Watch for a small light flash or listen for a beep from your car. Some models, like Aston Martin Vanquish or DB7 Volante, may have specific cues.
  5. Test your key fob

    Remove it from the ignition and step away from the vehicle. Press "lock" or "unlock" on your fob to check its range and connection.

  6. Repeat if needed

    Rarely does programming succeed on the first go every time! Follow steps carefully again if signals fail.

  7. Contact a dealer if problems persist

    Visit an Aston Martin dealership or Sure Lock & Key service online if these steps don’t work. They specialise in advanced coding issues using tools like ThinkDiag scanners.

  8. Have spare keys ready

    Always keep backup crystal keys handy, especially older models like DB7 Vantage Volante or newer ones such as Aston Martin Virage.

These steps ensure smooth programming without delays!

Addressing Signal Interference

Signal interference can disrupt how your Aston Martin key fob works. It may stop locking or unlocking your car properly. Here are some simple ways to handle it:

  1. Keep Away from Electronics

    Placing the key fob near devices like phones, tablets, or laptops can interfere with its signal. Keep it clear of gadgets to avoid issues.

  2. Avoid Crowded Frequency Areas

    Busy places with wireless signals, like shopping centres or airports, might block your key fob's range. Step away from dense areas and try again.

  3. Check Car Battery Health

    A weak car battery may reduce signal reception for the fob system. Get your car battery checked by an auto mechanic if problems persist.

  4. Replace Key Fob Battery

    Low battery in the fob itself is another reason for connection troubles. Replace the battery using a compatible new key battery, such as for Volvo or Jaguar models.

  5. Inspect Windscreen Tinting

    Some added tints on luxury cars like Aston Martins or even Porsche may have metallic layers blocking signals. If tinted screens cause trouble, consult a professional about removing them.

  6. Store in Signal-Blocking Pouch

    Protect your plastic key or crystal key design from relay attacks by storing it in a Faraday pouch at home or while travelling.

  7. Move Away From Large Vehicles

    Parking near lorries, buses, or big SUVs like those by GMC and Chevy can sometimes create signal blocks due to size and metal coverage.

  8. Reset Key Fob System

    Sometimes resetting the entire starter system can fix communication failures between the car and the valet fob.

Security Tips for Your Key Fob

Security Tips for Your Key Fob

 

Keep your key fob away from doors and windows to stop thieves from intercepting its signal. Use a signal-blocking pouch, also called a Faraday bag, for extra peace of mind.

Avoid Replay Attacks

Hackers can clone your key fob's signal using replay attacks. They record the code it sends and use it later to unlock your car. To stop this, upgrade your security. Aston Martin owners should consider fobs with changing codes or encryption tech.

Store the fob in a signal-blocking pouch when not driving. This stops unwanted signals from reaching it. Thieves may lurk near homes, waiting for a chance to copy signals—don't make it easy for them.

 

"A small habit like blocking signals can save you big headaches."

 

Store the Fob in a Signal-Blocking Pouch

Relay attacks exploit key fob signals to access cars like your Aston Martin. A signal-blocking pouch stops these threats in their tracks. These pouches, often lined with materials like Faraday fabric, block wireless signals from escaping or being intercepted.

Luxury vehicle owners use them as an extra layer of protection for crystal keys and lock systems. Check the pouch regularly for wear and tear to keep it effective. Think of this as a simple way to shield your car’s ignition system against sneaky tricks.

How to Replace a Lost or Damaged Key Fob

Losing your Aston Martin key fob can feel like losing a piece of treasure. To get back on track, act fast and reach out to the right professionals for help.

Contacting Aston Martin Dealerships

Dealing with a lost or damaged Aston Martin key fob can be frustrating. Contacting an authorised dealership is the best way to get a replacement.

  1. Locate Your Nearest Dealership

    Use Aston Martin’s website or call their customer service line to find the closest dealer. Ensure it’s an official one, as they have the right tools and expertise.

  2. Prepare Your Vehicle Details

    Write down your car's VIN (Vehicle Identification Number). It’s usually on your registration papers or visible through the windshield. Dealers will need this to identify your car.

  3. Bring Proof of Ownership

    Carry documents like your registration and ID showing you own the vehicle. This step prevents someone from getting keys for a car they don’t own.

  4. Ask About Key Coding Services

    Aston Martin key coding requires dealership equipment, which third-party services might not have. Request details about programming the new fob while enquiring to save a second trip.

  5. Check Costs Beforehand

    Replacement key fobs can cost hundreds, sometimes up to $800 or $1,000 depending on the model year and type of crystal key you need.

  6. Schedule an Appointment

    Confirm a time for both purchasing and programming your working keys, as this process may take several hours at some dealers.

  7. Enquire About Additional Keys

    It’s wise to order spare fobs if needed—Aston Martins come with three keys originally, but extras may prevent future headaches.

  8. Consider Towing If Necessary

    A dead battery in your current fob could leave you stranded, requiring towing services to bring your vehicle directly to the dealership for repairs or replacements.

Programming a New Key Fob

Getting a new Aston Martin key fob isn’t just about getting it cut—it needs programming too. This step links the fob to your car’s system for smooth operation.

  1. Visit an authorised Aston Martin dealership. Only they have access to the proper tools and software required for this process.
  2. Provide proof of ownership. Bring your vehicle registration and personal ID, as dealerships require this for security reasons.
  3. Ensure the replacement matches your car model. Key fobs are not universal across all Aston Martin vehicles, so confirm compatibility first.
  4. The dealership connects the key fob to your car's onboard computer system. This uses specialised coding equipment they have on-site.
  5. Test all functions before leaving. Make sure locking, unlocking, and starting the car work without issues.
  6. Expect programming fees in addition to the cost of the key fob itself. Pricing varies but can reach several hundred dollars depending on services needed.
  7. Always program any spare or backup keys at the same time if possible. This avoids future errors with mismatched coding between keys and vehicle systems.

Conclusion

Taking care of your Aston Martin key fob is simple but crucial. Replace the battery on time, and keep it secure from signal theft. Always have a backup plan for lost or damaged keys by contacting dealerships when needed.

A little effort goes a long way in keeping your car safe and functional!
