Lost Car Keys Replaced in Sutton & South London
Lost your only set of car keys? Do not panic and do not pay a fortune to the dealer. Our mobile auto locksmiths specialise in all-keys-lost work, coming to your vehicle to generate a brand-new key from scratch and get you driving again the same day.
When every key is gone there is nothing to copy, so we build a key from your vehicle data instead. We read the mechanical key code from the door lock or your VIN to cut the correct blade, then recover the immobiliser security data needed to code a working transponder.
Crucially, an all-keys-lost job is also a security job. We delete the lost key from the vehicle memory so it can never start your car again, even if it falls into the wrong hands, and then program a fresh, fully working key into the cleared immobiliser.
We provide an itemised receipt for every all-keys-lost replacement, which is exactly what your insurer or fleet manager needs to process a claim. Confirm your registration with us first and we will quote a fixed price before any work begins.

Vehicle Brands We Commonly Support
We cover most makes and models. If yours isn't listed, just ask — send your make, model and year for a quick check.
Please note: final availability and price depend on your vehicle's make, model, year, key type, security system and location. We confirm both before attending — no obligation.
How It Works
A clear, four-step process — from your first call to a job done right.
Tell Us the Reg
Send your registration, make and model so we can confirm the key type, source the right blank and quote a fixed price.
Read the Security Data
At your vehicle we read the key code from the lock or VIN and recover the immobiliser PIN, by OBD or EEPROM where required.
Erase & Recode
We delete all previously coded keys from memory so the lost set cannot start the car, then cut and program a fresh working key.
Drive Away
We test locking and engine start, hand over your new key and a receipt for your insurer, and you pay the agreed price.

Frequently Asked Questions
I have lost every key with no spare, can you still help?
Yes, this is exactly what we specialise in. With no key to copy we read the mechanical code from your lock or VIN to cut a new blade, recover the immobiliser security data and program a brand-new working key at your vehicle.
Will the lost key still work after you replace it?
No. As part of every all-keys-lost job we erase all previously coded keys from the immobiliser, so any lost or stolen key is permanently locked out and can no longer unlock or start your car.
Do you provide a receipt for my insurance?
Yes. We supply an itemised receipt showing the work carried out and the parts used, which is the document your insurer or fleet manager normally needs to process a lost-key claim.
Is this cheaper than going to the main dealer?
Usually significantly so, and far quicker. A dealer often requires the car recovered to site and a key ordered in, whereas we come to you and complete most all-keys-lost replacements the same day for a fixed price.
Can you replace a lost keyless smart key?
Yes. We regenerate and program proximity smart keys as well as traditional keys. Smart keys take specialist equipment and a little more time, but we confirm keyless entry and push-button start before we leave.
