Alarm

[Steve in San Diego]

On my 91 LS400 when unlocking the driver's door occasionally sets off the alarm. If I lock & unlock with the key several times it will stop. The ignition was replaced about 90,000 miles ago and new keys were made. Has anyone else had this problem? Is there a fix?

Thanks B)

i have been having this issue recently. i thinkyou are unlocking it too fast.

when i turn mine too fast and nto al the way, then try to pull the key out, it will lock all 3 doors (the dirvers rear doesnt work) and the alarm will go off until you turn the key toward the back of the car 3 times.

these cars are old and sometimes they dont always work the way they should. i shouldnt think its a big deal. just kind of emarrasing in a crowded parking lot.
