Another ls400 curveball...
I have a, what looks like a aftermarket key fob which has a lock unlock and boot open features.
The lock has never worked until today, randomly. The lock worked but the unlock did not so I unlocked it manually and the alarm went off....... and will not stop.
When I manually lock the car the alarm will turn off after a couple of seconds.
New battery, new key battery, car turns over and runs, everything works but the alarm goes off.
I do have another key without buttons on it, I don't know what good that will do.
Does anyone have any ideas or tips and tricks?
