*All keys need to be present at the time of coding, if you leave any at home or find a previously lost key then they will no longer work following the re-coding. Only keys present at the time of coding the remote key fobs will work again.*


Need a spare car key? 

If you only have one key for your car we are able to produce duplicate keys. Depending on the type of transponder chip used we may be able to make a direct copy of your coded car key. This type of car key replacement is produced utilising sophisticated equipment to copy the code onto a new transponder chip. Most new cars however, use an encrypted chip which can not be copied. In this instance we are able to produce a new key and code it directly to your vehicle using our diagnostic tools.


Need a repair to your remote key fob?

We also offer a service providing repairs to the remote control buttons, micro switches attached to the main board and replacing the outer casing for a new ones so your key looks and feels like new again.

Why buy a new one! For under half the price of a new one French Diagnostic Services can recondition your old remote. New batteries are supplied with any reconditioned remote, whatever the problem.
