My electric car key suddenly stopped working - no remote central locking any more - I had to use manual locking. These keys go kaput if you if you fiddle with the off/on buttons, have too many operations out-of-distance or the kids fiddle with them and exceed the programming tolerance.
To get them going again is a simple matter of synchronizing.
A local dealer waffled about how difficult a problem this is, with re-programming, new chips, synchronizing etc. - oh, big problem and said it would cost GBP 165. WOW ! What a money making con-trick conveniently forced onto the vulnerable and non-technically minded majority, especially women and the elderly. It is a 99% probability that if the battery is OK, all it takes is less than two minutes sat in the car. No world shattering high-tech electronic tom-foolery, just a few simple twists, turns and button pressings.
I have spent my whole life on mechanical and electronic matters and am technically minded. Not easy to con and not easy in giving up on a problem.
After a quick surf of the web to see what it is all about, the remedy was easy. There were several quite easy methods of getting these keys to work again when they have failed, no vast amount of expense, just a few seconds or minutes sat in the car. I went for this :-
Sat in the car with the door shut, inserted the key in the ignition, turned it on and of within 2 seconds.each time. Opened the door twice with the ignition turned on, then turned it off. Turned on the ignition again and pressed the lock and unlock buttons on the key together - both at the same time. The lock worked immediately. It all took about 1 minute.
Problem solved, key now works fine.
One reference was this :-
The other link which gave me the main clue was this :-
Answer ONE - with some input from the first link.
