The Process:

What Will does when he arrives:

1Verifies your identity and ownership

For your security, Will will ask to see proof that you are the registered keeper or an authorised person: typically your V5C logbook, driving licence or insurance certificate. This is standard practice and protects you as the vehicle owner.

2Deactivates the stolen key

Using specialist programming equipment, Will erases the stolen key from your vehicle’s immobiliser system so it can no longer be used to access or start your vehicle. This is the most critical step in securing your car after a theft.

3Cuts and programmes replacement keys

Will then cuts and programmes brand new replacement keys on-site. These are fully programmed to your vehicle’s immobiliser, central locking and (where applicable) keyless entry system. Your existing working keys (if you have any) are re-registered at the same time.

4Tests everything before leaving

Before Will leaves, he’ll fully test your new keys: Locking, unlocking and starting the vehicle, so you can be confident the job is complete and your vehicle is secure. He’ll also talk you through what to do next if needed.

5Advises on next steps

Will is happy to advise on anything else relevant to your situation: Whether that’s additional security measures, what to report to your insurer, or whether a lock change is advisable depending on your circumstances.

We Fix Stolen Key Problems!

Don’t delay

Why you need to act quickly:

Your vehicle is at risk

Modern car keys contain a programmed transponder chip linked directly to your vehicle’s immobiliser.

Until that key is deactivated, whoever has it can unlock and start your car at any time.

Thieves know your address

If your keys were stolen in a burglary or alongside your wallet, there’s a good chance the thief also has your address.

From your driving licence, insurance documents or post. Don’t leave your vehicle parked outside.

Insurance implications

Failing to take reasonable steps to secure your vehicle after a key theft could affect a future insurance claim.

Acting promptly and keeping records demonstrates due diligence to your insurer.

Peace of mind

Until the stolen key is deactivated and new keys are programmed, you may feel unsafe leaving your vehicle unattended.

Getting it sorted quickly means you can move on with less stress.

Spare Vehicle Key FAQs:

Can someone use a stolen key to take my car?

Yes.

Until the stolen key is deactivated from your vehicle’s immobiliser system, it will work exactly as it did before.

A thief with your key can unlock and start your vehicle without triggering any alarms. This is why acting quickly is so important.

Modern car keys contain a programmed transponder chip that communicates with your vehicle’s immobiliser.

Until that chip is erased from the system, the key remains live.

Will can deactivate it remotely from the vehicle’s onboard system, no dealership visit required.

My keys were stolen in a burglary and the thief has my address. What should I do?

This is an unfortunately common scenario and it’s important to act fast. Your immediate priorities are:

  • Report the burglary to the police and obtain a crime reference number
  • Move your vehicle away from your home address if you have a spare key
  • Contact Will to get the stolen key deactivated and new keys issued as soon as possible
  • Notify your home and vehicle insurers

Important: Do not assume that because nothing has happened immediately, the risk has passed.

Opportunistic thieves may wait before acting.

Opportunistic thieves may wait before acting.

Should I also change the locks on my car?

In most cases, deactivating the stolen transponder key and reprogramming the immobiliser is sufficient to secure your vehicle.

However, if your vehicle uses a physical barrel lock that the stolen key matches, there may be a case for lock replacement, particularly if the theft was targeted rather than opportunistic.

Will can assess your specific situation when he arrives and advise whether any additional measures are recommended.

Will my car insurance cover the cost of replacing stolen keys?

Many comprehensive car insurance policies include cover for key replacement following theft, though this varies significantly between providers.

Some policies require a specific police report and crime reference number before they will process a claim.

It’s worth checking your policy documents or calling your insurer before booking.

Even if your policy does cover it, our prices are often lower than the insurer’s approved rates.

We can provide a full itemised invoice for any claim you wish to make.

Tip: Always keep your crime reference number safe. Without it, most insurers won’t process a key theft claim.

How much does it cost to replace stolen car keys?

The cost depends on your vehicle’s make and model and the type of key technology it uses.

Basic transponder keys are less expensive to replace than full proximity smart keys on premium vehicles.

We always provide a free, no-obligation quote before any work begins.

As a benchmark, our prices are consistently and significantly lower than main dealer alternatives:  Typically by 30–50%

… With no call-out fees and no hidden charges.

Can I claim for a replacement key if it was stolen from my home?

If the keys were stolen during a home burglary, the replacement may fall under your home contents insurance rather than (or in addition to) your vehicle insurance.

It’s worth checking both policies.

Either way, you’ll need the police crime reference number and documentation of the work carried out.

Will can provide a full invoice.

Can You help with vans and commercial vehicles?

Absolutely! 

From the moment you get in touch, we will let you know if we cover your make, model and vehicle type. 

There are very few vehicles that we cannot assist with. 

Can you programme more than one key?

Yes, and we can usually offer the second (Or third, or forth!) key at a discounted rate.

Much of our fee is there to cover travel and time, so we can be verfy competitive on multiple keys.

What proof of ownership do I need?

For security reasons, Will requires evidence that you are the registered keeper or an authorised person before working on any vehicle.

Accepted documents include:

  • V5C logbook (vehicle registration document)
  • Valid driving licence matching the registered address
  • An insurance certificate showing the vehicle registration
  • Finance or lease agreement in your name

This is a firm requirement, not a formality.

It exists to protect vehicle owners from unauthorised key cutting, which is especially important in cases of suspected theft.

Can you replace keys for any type of vehicle?

Will carries equipment for a very wide range of makes and models, including cars, vans and HGVs.

He regularly works with vehicles from:

Audi, BMW, Ford, Land Rover, Mercedes-Benz, Range Rover, Toyota, Vauxhall, Volkswagen and many more.

If you’re unsure whether your vehicle is covered, just call, and he’ll confirm before travelling to you.

I still have one key. Can you deactivate just the stolen one?

Yes.

Will can erase only the stolen key from your vehicle’s immobiliser system while keeping your remaining key or keys active.

This is a standard part of the process and ensures you’re not left without access to your vehicle.

Your existing keys are re-registered at the same time, so everything continues to work seamlessly.

Do you cover the whole of Sussex?

Will is based in Haywards Heath and covers approximately 40 miles, including:

Brighton, Crawley, Worthing, Horsham, Burgess Hill, Hailsham, Crowborough, East Grinstead, Dorking, Oxted, Reigate, Caterham, Edenbridge, Storrington, Steyning, Newhaven, Polegate and more.
