A customer in Northampton had completely lost all keys to their Hyundai i30 — no original, no spare, no way in. We attended on-site and had a fully working replacement key programmed within the hour, without needing to tow the car anywhere.
All Keys Lost — What's Involved
When every key to a car is lost, the process is more involved than adding a spare alongside an existing key. With no working key present, we need to perform a full immobiliser reset — wiping the existing key data from the car's ECU and writing one or more new keys from scratch.
On the Hyundai i30, this requires connecting professional diagnostic equipment to the OBD port and using specific security procedures to access the immobiliser module. It's a job that demands the right tools and knowledge — not something a standard locksmith or tow company can do.
We arrived, carried out the reset, cut and programmed a new key, and left the customer driving again.
How Much Does All Keys Lost Cost?
All-keys-lost jobs cost more than a simple spare because of the additional diagnostic work involved. For most popular models like the Hyundai i30, we can give a clear price over the phone before attending — no hidden fees, no surprises on arrival. See our car key replacement cost guide for a general comparison between mobile locksmiths and dealers.
