Lost Car Keys New Key Created On-Site — Devon, Dorset & Somerset
Lost all your car keys with no spare? You don't need the original key to get a new one. Using your vehicle's VIN and our AUTEL diagnostic equipment, DB Car Keys creates a brand new key from scratch — blade cut, transponder programmed, old keys deleted from your ECU for security — all at your location, 24 hours a day.
Lost All Your Keys? Here's Exactly What Happens Next
Losing your only set of car keys is one of the most stressful situations a driver can face. Unlike a lockout — where the keys are close by and the fix is straightforward — a lost key situation means creating a completely new key from scratch. This isn't something a key cutting stall, a garage or even most locksmiths can do. It requires specialist automotive diagnostic equipment that can read your vehicle's ECU and generate a new cryptographic pairing from your VIN.
DB Car Keys carries AUTEL and Xhorse OBD diagnostic tools capable of creating a new key for the vast majority of vehicles on UK roads — without any original present. We also delete all previously registered keys from the ECU, so any lost or stolen keys are permanently disabled and can never start your car again.
📍 Real Callout — Lyme Regis, Dorset
"A couple on holiday in Lyme Regis lost their keys somewhere on the beach — dropped from a pocket during a swim. They had no spare at home, were 200 miles from their house, and the nearest Vauxhall dealer couldn't help for 5 days. We attended within 30 minutes, created a new Vauxhall Astra key from the VIN, deleted the lost key from the ECU, and they were driving back to their holiday cottage the same afternoon."
📍 Real Callout — Dartmoor, Devon
"A walker lost their Ford Focus keys somewhere on a Dartmoor route near Okehampton — realised at the car park, searched twice, no keys. Miles from the nearest town, no signal, had to walk to get help. They called us once they got a signal. We reached the car park within 50 minutes, created a new key from the VIN using our AUTEL, deleted the original from the ECU. The customer was driving home before dark."
📍 Real Callout — Taunton, Somerset
"A BMW 3 Series owner in Taunton had their keys stolen from their jacket at a bar — including the car key and house key. Understandably alarmed — the thief potentially knew where the car was parked. We attended immediately, created a new key for the BMW, and crucially deleted the stolen key from the CAS system so the car could not be started by anyone holding the stolen key."

How We Create a New Key Without the Original
From your call to driving away — a single visit, no towing, no dealer wait
You Call
Tell us your make, model and location. Have your V5C registration document handy if possible. We give an ETA and head straight to you.
Ownership Verified
We verify you own the vehicle using your V5C and photo ID before any work begins. This protects you and ensures security.
Key Created
AUTEL connects via OBD. New key blank cut to your lock profile. Transponder chip coded to your ECU. All done at your vehicle.
Lost Keys Deleted
Every previously registered key — including lost or stolen ones — deleted from the ECU. They can never start your car again.
Tested & Done
New key tested — locks, unlocks, starts engine, remote functions all confirmed working before we leave.
Security note: Deleting lost or stolen keys from your ECU is important — anyone holding a lost key could potentially use it to start your car. When we create your new key, we delete all previously registered keys simultaneously. Your old keys are permanently deactivated. If your keys were stolen, this step is especially critical.
Every Type of Lost Key We Replace
Blade cut and chip programmed on-site for every key type on UK roads today
Transponder Key
The most common key type on UK roads. Plastic head with encrypted chip. Blade cut to your lock profile, chip coded to ECU via OBD. The vast majority of post-2000 vehicles use transponder keys.
Smart Key / Proximity Fob
Push-button start vehicles. The fob communicates via radio frequency — no blade insertion. Replacement requires advanced OBD programming. Available for most common makes with smart key systems.
Remote Flip Key
Blade folds into the fob body. Both blade and remote need to be matched — blade cut to your exact profile, remote programmed to your vehicle's receiver. Very common on French and German makes.
Key Card
Renault's credit-card-style key. We carry Renault card blanks in stock for the most common models. Lost card programmed on-site — one of our fastest lost key jobs at under 30 minutes.
