General Advice and Tips for Replacing your Key Case

Here are some general tips to follow whilst replacing your key case:

Always work on a clean flat area preferably with a white background and good lighting. Because car keys contain small parts it is important to be able to see any parts that may fall out.

Double check for any screws. If you are applying pressure and the key is not coming apart check for screws. Sometimes they can be hidden behind the manufacturers badge.

Be careful with any tools you are using. If you are using a tool to pry the case apart be careful not to injury yourself.

DON’T throw your old case away until you have tested that the new key works. If you try the new key and the car won’t start it means you have not transferred over the transponder immobiliser chip. Sometimes this chip is not on the main circuit board. If this is the case hold the old key close to the vehicle as well as the new one. It should now start. You will now have to carefully look for the transponder chip.
