When a car key is lost or stolen, simply getting a new key made does not address the security risk. The lost or stolen key still contains the electronic credentials that allow it to start your vehicle. If someone finds or takes your keys and knows where your car is, they can potentially access and start it.
This risk is higher in situations where your keys and your vehicle are connected: keys lost near where your car is parked, stolen along with a bag that contained your address or a car park ticket, or taken in a burglary where the thief can see your car outside.
Key deletion addresses this by removing the old key's credentials from the vehicle's security system, so even if someone has the physical key, it will no longer start your car.
Key deletion, sometimes called key erasure or key removal, is a process carried out using specialist diagnostic equipment connected to your vehicle's OBD port. The process reads the current key list held in the vehicle's immobiliser or ECU, removes the keys you want to invalidate, and retains or adds the keys you want to keep active.
It is important to understand that deletion always needs to be combined with the production of at least one new key, because the process of erasing all existing keys removes access entirely until new keys are programmed in.
Key deletion is supported on a wide range of modern vehicles, but the capability and process varies significantly between manufacturers and models. Some systems allow full deletion of individual keys; others only allow all keys to be erased and replaced simultaneously.
When you call us, we will confirm whether key deletion is supported on your specific vehicle, what the process involves, and what the most appropriate approach is for your situation. We do not proceed with any work until this has been confirmed and you are happy with the plan.
In almost all cases, key deletion is carried out as part of a combined process: old compromised keys are removed from the system, and new keys are programmed in their place. This ensures you leave with a vehicle that is both secure and accessible.
We carry both the deletion and programming equipment on every mobile visit, so this can be completed on-site at your location in Leeds in a single call-out.

Stolen car keys: immediate action checklist
- ✓Report the theft to West Yorkshire Police and obtain a crime reference number
- ✓Do not move your vehicle to a different location as this may help prevent it being found by whoever took the keys
- ✓Call your insurance company to report the incident and check your policy for key cover
- ✓Contact us to discuss key deletion and replacement as soon as possible
- ✓Have your vehicle make, model, year, and registration ready when you call
- ✓Have your photo ID and proof of keeper available (V5C or insurance document)
- ✓Consider whether the thief could identify the location of your vehicle from anything in the bag or wallet the keys were taken from
Key deletion and reprogramming requires specialist diagnostic equipment and a thorough understanding of vehicle security systems. Choose a locksmith who confirms deletion capability for your specific vehicle before quoting, who carries out both deletion and new key programming in a single visit, and who can explain clearly what the process involves. Be wary of anyone who offers key deletion without first establishing which system your vehicle uses.
Call us 24/7. We will confirm your situation, talk you through the options, and aim to get you sorted fast.
Can you delete a specific key from my vehicle without affecting the others? +
On many systems yes. The exact capability depends on your vehicle make and model, which we confirm before starting any work.
Does key deletion work if the thief has already used the key to access the vehicle? +
If the vehicle has not been moved, key deletion still removes the electronic access the stolen key provides. If the vehicle has already been taken, contact the police immediately.
Do I need to be with the car for key deletion? +
Yes. The work is carried out at the vehicle using diagnostic equipment connected to the OBD port. We come to wherever the car is.
How long does key deletion take? +
The process typically takes 30 to 90 minutes depending on the vehicle system and the number of keys being deleted and replaced.
Can you delete keys and make new ones in the same visit? +
Yes. This is the standard approach. We carry deletion and programming equipment on every mobile visit.
What if my vehicle does not support individual key deletion? +
Some systems require all keys to be erased and replaced simultaneously. We will confirm which applies to your vehicle before starting work.
Do you offer Emergency Locksmith Service for stolen keys? +
Yes. If your keys have been stolen and you are concerned about your vehicle's security, call our Emergency Locksmith Service immediately. We cover Leeds 24/7.
Is there a call-out fee? +
No. Clear upfront quote before we travel. The price on the phone is what you pay.
