So it could be a dirty battery contact, or even the new battery being duff. That's my guess anyway.

Back to key number 1 - I have today, finally (after 6 years !!!!!!!!!!!!!!!)soldered in a replacement microswitch but the key was still dead - so I replaced the battery and the little light in the key came on for about 15 secs and then went out. However, the key still won't lock or unlock the car and the light on the key doesn't come on when either of the buttons are pressed . . .
Hope you're keeping up with me here ? . . .
So, my question is . . . what is my question???? . . .oh yeah, has the key just lost its coding because its had a dead battery in it for X number of years, or is it likely to be not working for other reasons?
