New Key fob - how to remove blade from original

john116 · 9th September 2019, 08:47

Hi - have searched on this forum, but have found so far no definitive way on how to remove the metal key blade from the fob plastic, to insert it into a new fob plastic case. Help appreciated!

I know I have to transfer the transponder as well, but can't work out how the blade comes off/out.

Thanks,
John

Brian's tea method works well - boil two cups of water, one for yourself and the other to immerse the bladed part of the keyfob in hot water. By the time you've finished your tea the plastic is now quite soft and the blade and holder can usually be pulled from the keyfob.

Otherwise cut with a hacksaw, or craft-knife the softer keyfob plastic around the blade holder which is harder plastic.

Don't bother trying to remove the transponder chip, just work on the upper part of the keyfob and retain the other half, as the back (which holds the transponder chip) is probably Valeo, then it's better quality than any new one.

So can you just put the transponder chip from the key near the steering column, and then not worry about having them in every key?

Its the ring around the ignition lock that reads the transponder, don't know how close they need to be. I doubt if your insurance would be impressed if you fixed the transponder in the car rendering the immobiliser useless.

He means to just use just the button part of the new key fob and keep the old Valeo one with the transponder in it. They usually fit together fine (old and new).

No, if the chip were located by the steering column then the car would be easy to steal.
I'm merely suggesting that instead of removing the chip and putting that in a new back section, keep the old rear section of your current keyfob and fit that to your new front.

Most of my cars don't have immobilisation. Just a key. They haven't been stolen yet. Re insurance, I don't have it insured, so that's no problem. Might do some tests as to how close it has to be.

You sure about no immobilisation, or are you talking about other cars than the Rover 75? Fitted as standard on the 75 so unless someone has been doing some magic inside your main ECU (EMU) it's there - why else would you be questioning how close to put the transponder chip? And why bother re-locating the transponder chip, it's current placement is ideal.

Yes, other cars. All my 50s and 70s cars. I'll probably leave the chip in the keys, just curious to see how close it needs to be. Although personally, I think the whole immobilisation thing is unnecessary.

I can answer that one for you - the range is 2 centimetres
