What Affects the Price?
Key Type
The biggest pricing driver is the key type. A basic cut key for a pre-1995 vehicle with no electronics is almost trivially cheap. A smart key for a current BMW or Mercedes requires specialist diagnostic access and proprietary software licences — hence the higher cost. See our transponder vs smart key guide for a plain-language explanation of the differences.
All Keys Lost vs Key Addition
Having a working spare key makes replacement significantly simpler and cheaper. The locksmith programmes the new key alongside the existing one — no ECU access required, no immobiliser reset. If all keys are genuinely lost, the ECU must be accessed and the key register wiped — a more involved process that takes longer and costs more.
Vehicle Make and Model
Some manufacturers use proprietary immobiliser systems that require specific software licences or hardware adapters to programme. Land Rover and Jaguar, for example, tend to cost more than Ford or Vauxhall because of the additional equipment required.
What You Should Always Ask For
Before any locksmith attends, ask for a fixed all-in price that includes the call-out, the key blank, cutting, and programming. If they won't give you a fixed price, don't use them. Legitimate locksmiths can and do give fixed quotes over the phone — it's a basic professional standard.
