Key Issues Ls400

[jigmaster flash]

With my recent ls400 purchase I got three keys - two remotes and a non remote.

One remote works fine.

The second remote door lock and unlock functions do not work and the indicator light does not flash. THe boot unlock button does work though,and the red indicator light flashes when pushed. Am I to presume this second remote key is buggered ?

The third key is a full size one but without remote buttons, I tried unlocking the car with this and the alarm went off! what is this keys function?

The gray key, Its a valet key you can lock the glove box & boot opening pull so nothing gets stolen when your car is being parked at the hotel.

Cheers mark, that solves the riddle of the grey key.

I took the non-working spare remote apart and the pressure contacts for unlock/lock have broken off the circuit board, which was rusty too so obviously dropped in liquid at some point. Cleaned up the board as much as I dare and luckily it works manually on all locks and ignition so still a spare!

Just make sure its nice and dry by leaving it near a heater overnight. Mike

I think if you lock the car with the fob but unlock with the key the alarm will go off as the immobiliser is still set
