Default Replace car key case

Can anyone please tell me how to change the case on my car key? I bought two new cases as the button part of the case has perished. The original car key ( metal bit that goes into the door) won’t pull out. Is there a video that shows you how to do this? Thanks for any reply. Alex (bigcar)

I gripped the metal part of the key with a pair of mole grips locked on, took a firm grip of the case and with a bit of teasing, it came away without too much fuss. The hardest part for me was getting the all important transponder (the black oblong microchip doodah) out without damage (key won't work/start car without it). On my second case, I just swapped the button part on top of the case, onto my old case as it did fit OK and left all the bits in.

Ok the way I do this is to prise the case open and take the electronic board with the battery attached out and put it away safely.
Put away the other half of the case which contains the transponder ensuring this does not fall off.
Boil the kettle with water and switch it off before it starts to boil like mad pour enough water in a suitable container and put the half of the case to which the blade is attached, leave for 10-12 mins to soften the plastic enough to enable you to wiggle the blade out of its attachment take your time and it will come out with the rubber collet attached to it, loose the collet or damage it badly and the game is over. Then push the blade into new case, soften in hot water as needed, transfer the electronic over, and transponder into new other half of case and close case, then test on car the ensure it works. TAKE YOUR TIME!!!!

Question Suggestions?

Mario - can you suggest anything for my key?

Here's what I've got after failing to separate the parts of the old key properly. As you can see, parts A and B (the red ones) are no longer attached to the old case but red part B is damaged (it should look like blue part B).

Blue parts A, B, C, D, are all new.

Can it be salvaged or do I need to get blue part A cut to match red part A?






EDIT

Or, another idea altogether:

- Buy a completely new lockset containing: 2 pre-cut keys with transponders; one lock barrel; one back plate.

Then do this:

- Ditch the new backplate
- Take the old lock barrel off the car's driver's door and fit the new one in its place
- Ditch the new transponders and replace them with the car's original ones

This plan might work for the driver's door but what about the manual lock on the boot lid (which would still have the original lock barrel)?

Your could also buy two new keys precut to match your original locks, so no need to swap locks or have different keys for the boot etc.
