Hey guys, my mum had a spare "car key" (electronic, push the button it unlocks no other buttons simple) and it wasn't working...thought ok i'll take a look at it seeing as it doesn't work what can go wrong, checked battery with multimeter put it all back together and it didn't work, so I was like ah well. Then for some reason i pulled apart the working one and well now it doesn't work!! I checked the battery with the multimeter (both are fine and working) and all I did was pull the battery out and try it in the other one. Car still starts/locks (when you push the key in and turn the lock - it locks all the other doors) but now when you push the button it doesn't lock/un-lock like it used to. I didn't touch anything inside I didn't solder anything etc NOTHING!! I though maybe I have to reset it or something, so I pulled the neg of the battery left it off for like 20secs, put it back on then tried again nothing! I have checked all the fuses and none are dead (if 1 was dead I would know because 1 fuse sort of controls two things - i.e like the door locking one, if it's blown it won't lock and the radio will not turn on...radio still turns on so it's not dead none are). Please help me, I have to repair it (mums not really fussed but still) it's $150 for a replacement :0 I figure all they do is get the code of the chip put a new one in bingo $150...dam it. Please help me please!!!!!!! Car is a 95' Toyota Lexen
gigabite - Please!!
EDIT: I know why the spare key wasn't working, one day my mum dropped it and it cracked teh solder on one point, re soldered it but still no go!
