v reg 406 hdi key fob working intermitinly

[shaun406]

my key fob some times works and some times doesnt is there any reason why this is happening,does it need reprogramming the battery in the fob is new.so how do you reprogram it if someone could give me a pointer i would be really grateful.

Mine seems to do this an odd time too. Never found a reason, but I have realised that if you re-try within a few seconds it never works. Leave it for say 30 seconds & it always works! I know this suggests a low battery, but it tests OK.

iv'e just bought a 406 lx off my uncle and he said that the key fob hadn't worked for 4 years.so i bought a new battery.that didn't work.i then took out the small circit board and the switch button had come off.i got a very fine soldering tip for my soldering gun and stuck it back on .then to program it in i followed the instructions in my hand book and low and behold it works fine.

Nice job! It's about time someone had some luck with keys

You shouldn't use a soldering gun for small low voltage pcb work like in a key though, they're far too powerful and usually a lot hotter than irons too. I've seen a few boards that have been fried by those things! You're best off with a small iron...

HI AGAIN.THE GUN I USED FOR SOLDERING BACK THE BUTTON ON THE CIRCIT BOARD IS A BENZOMATIC GAS GUN WITH A VERY FINE TIP.DARE NOT USE ELECRIC SOLDERING IRON.
