When your car keys are stolen — whether from your home, pocket, or workplace — the immediate concern is obvious: someone has a key that can start your vehicle. What many drivers don't realise is that simply having the car re-keyed isn't enough if the original keys are still programmed into the ECU. The vehicle's immobiliser holds a list of authorised key codes, and unless the stolen key's code is explicitly deleted from that list, it will still start the car. Excalibur's lost and stolen key deletion service removes all previously programmed keys from the ECU, then re-programs new keys — leaving the old stolen key completely dead.
The process of deleting keys from an immobiliser requires the same dealer-grade diagnostic equipment as key programming — you need to access the ECU, authenticate with the correct security credentials, and overwrite or remove the stored key codes. This is not something that can be done with generic tools or a code reader — it requires manufacturer-specific software with the appropriate access level. Main dealers will perform this service, but typically only during business hours, after a significant wait, and at a cost that reflects their overheads. Excalibur provides the same technically identical service, mobile, 24/7, and at a fraction of the dealer cost.
If you've just discovered your keys are stolen, call Excalibur immediately — 07831 872 740. Ian or Adam will come to your vehicle, connect to the OBD port, delete all previously programmed keys from the immobiliser database, and programme a fresh set of new keys. This means the stolen key is completely useless for starting your vehicle. Combined with a change to your home security if the keys also included a house key or fob, you significantly reduce the risk of vehicle theft. Ian and Adam understand the urgency of this situation and will prioritise call-outs where security is at risk.
Beyond the immediate security concern, there are practical steps to consider after stolen key deletion. If the thieves know your vehicle's location, it may be worth moving the vehicle or informing the police before we arrive. Ian and Adam will always advise on the best order of operations. Over 30 years across the North West, they have handled countless stolen key situations, and they understand the anxiety that comes with it. The goal is to restore your sense of security as quickly as possible — a new set of keys in your hand and the old ones dead in the system.

How Much Does Lost & Stolen Key Deletion Cost?
The cost of lost & stolen key deletion depends on your vehicle's make, model, and the specific key type required. Excalibur is consistently 40–60% cheaper than main dealer pricing because we don't carry dealer overheads, and we use quality compatible components rather than OEM parts at manufacturer prices.

Lost & Stolen Key Deletion — Frequently Asked Questions
Report the theft to the police immediately and get a crime reference number — you'll need this for any insurance claim. If the thieves know your vehicle's location, consider whether you can safely move it before calling us. Call Excalibur on 07831 872 740 to arrange immediate key deletion and replacement. Do not leave the vehicle in the same location where the theft occurred if it can be avoided.
No. Once the key code is deleted from the immobiliser database, the key is recognised as unauthorised and the engine management system will prevent the engine from running. The key may still physically fit and turn the door lock if it was cut to the correct profile, but the immobiliser will ensure the engine does not start.
Many comprehensive insurance policies include key cover as standard or as an add-on. The crime reference number from your police report is usually required when making a claim. Check your policy documents or call your insurer before paying out of pocket — you may be entitled to full reimbursement. Excalibur can provide a receipt and job description that satisfies most insurance claim requirements.
The same process applies. While the risk profile is different — a lost key is less likely to be used maliciously — it's still worth deleting the lost key from the immobiliser, particularly if the key was lost in a public place with any connection to your vehicle (e.g., found near the car park where you usually park). We can combine the deletion and new key programming in a single visit.
Yes. Excalibur operates 24 hours a day, 7 days a week, 365 days a year. Stolen key situations are emergencies, and Ian and Adam treat them as such regardless of the time of day or night. Call 07831 872 740 at any hour.
