lexus toyota alarm system.

This may appear twice, sorry.



Anyone know about this scenario:



Went to my wife's Lexus (96 gs300) and found that the remote key fob had the operating light showing although no buttons were pressed ! Obviously it would not disarm the alarm/open the doors. I opened the door with the key and that set the alarm off, putting the key in would not shut down the alarm, but the engine started and after a few moments the alarm stopped and I drove home, as soon as I turned off the engine, the alarm went again. I opened up the remote to disconnect its battery and on reassembly the light was out. But now it won't turn off the alarm/unlock or lock the doors. I have tried re-synchronising the fob to the car (press unlock button till the light flashes, then the lock button, all in close proximity to the centre console) but no joy, the alarm is active permanently.



Now, before I admit defeat and go, credit card in hand to a Lexus dealer, does anyone have any ideas on this one?



I have tried leaving the battery disconnected overnight, but the alarm goes on reconnection. As a temp bodge I have disconnected the sounder (remove the RH indicator to gain access) But the hazards still flash for thirty seconds or so each time you start it up. I have googled and looked on the owners club, but they seem to have had similar problems without any mention of a cure. I have been told that my mobile phone may have spiked the remote ?



The system is Toyota TVSSIIIB

take the fob apart and find out why the light is on, is the button switch jammed down etc.....

the buttons were not jammed on, it appeared to be an electronic fault as a hard reset cured the fob problem, just that it now doesn't operate the car !

a silly, have u foned lexus to ask how to program a fob in, they may...tell u?

I would like to think that, but I doubt it, I'll probably visit a dealer next week, people are generally more helpful face to face, I think. Someone on an American newsgroup described the procedure as 'a chicken dance', so it sounds complicated! Meantime the flasher part of the alarm has stopped happening each time you start the car, so it is not so annoying, or urgent.
