Spare car key costs in 2026 vary wildly by make, model and key type. Here's what you should actually pay for a spare car key from a mobile auto locksmith in West London.
Basic flip key (Ford, Vauxhall, older VAG)
£90–£140 cut and programmed at your driveway.
Smart proximity key (modern VAG, BMW, Mercedes)
£180–£350 depending on security level and key shell.
Premium smart keys (Range Rover, Porsche, newer BMW)
£280–£550. These keys carry higher-grade security chips that take longer to program.
Van keys (Transit, Sprinter, Vivaro, Crafter)
£150–£300 depending on key type and immobiliser generation.
Why dealers charge double
A main dealer will quote £400–£800 for the same spare key — they pay franchise fees, mark up the key blank and bill an hour of workshop time even for a 30-minute job. A mobile auto locksmith is genuinely half the price for the same result.
Discount for a second key on the same visit
We give 25–35% off a second spare key cut and programmed on the same visit. Never run on just one key.
