Compare Jaguar S-Type key programming job quotes from specialist garages

In the late ‘90s, some car manufacturers started adding a specialised microchip to car keys to give their vehicles an extra level of security. If the vehicle doesn't detect the chip, it won't start. But what happens if you lose your keys? Who can programme car keys?

You need to find an emergency car locksmith who offers a car key programming service. This process involves reprogramming a blank chip to match your vehicle's current settings and putting it into a new key fob.

Most locksmiths offer mobile car key programming since you probably can't come to them without a working set of keys. Instead, they bring all the tools and equipment to you.

Do all car keys need to be programmed? This question is common among drivers; the answer is that almost all modern car keys contain a transponder chip and therefore have to be programmed.
