Replace Blade In Transponder Key (One Without The Buttons)

[dori2o]

I've recently paid the customary £160+ to get a new key/fob from the dealers and I can see why I was having so much trouble with the transponder key opening doors as it was so badly worn away. (I bought with only the transponder key, I know it was stupid)

 

Now I want to save myself some money if possible and replace the blade in the transponder key.

 

There are no screws on the casing but there is a line around the key which indicates it is likely 2 moulded plastic parts which are pushed together.

 

Is it easy/possible to just replace the blade with these type of transponder keys? I will obviously then have the blade cut from the new key.

I am not quite sure what keys you now have - is it a key without the remote locking buttons or a remote key - or is it a new and old key, both none remote ones. The following assumes you have a new key without the remote buttons and an old remote key with a worn key blade.

 

Best thing will be to get a new remote key case through ebay for about £5, take it to a key cutting place and get the blade cut to your new key blade. Then put the insides from your old remote key case in to the ebay one. This way you end up with a good remote key and a spare none remote key.

 

Note that the remote key blades can be removed by part opening the key blade so you can see at the case end a small roll pin in the blade - if you push out this roll pin the blade can be removed and swapped for another blade and the pin pushed back in.

 

If it is a none remote key on which you want to fit a new blade, then these seem quite solid so you can only try to break it to get the blade out, hoping the internal chip for the transponder is not damaged. You could also see how far away the key needs to be from the ignition for it to not work the immobiliser, if a few inches then you could just get a cheap key cut and clip it to your worn key.
