LS400 Alarm

[Kayjayem]

Hi I’ve just developed a problem (at 1.30am) with my LS400’s alarm. It went off for no obvious reason and I couldn’t turn it off with either of my two fobs, it only stopped when I got in and started the engine. I disconnected the Battery at this point. Anyone know anything about the alarm ? Where should I start looking or should I take it to a garage ?

Check the state of the car Battery and the Battery in your key fob if they are weak they will trigger the alarm.

when my Mk3 had the same issue a few years ago .......  underneath the wood trim encasing the gear knob, next to the centre armrest, there's a wind-down knob to turn off the sound .............  that's worked for me, from sound advice on the forum

that was after buggering about with the main Battery, fuses and all else ... my indy did it for me from this forum's advice ......  I guess you have to be gentle not to fracture the wood fascia

Good luck

Did you restart the car and the alarm was still engaged? That would be a BIG issue. Wonder what triggered it?
