Remote Unlock/key Needs Few Presses Before Opening Car? Ls400

[Yoda400]

Hi chaps

Our LS400 (1999) isn't unlocking on the first press of the key, well sometimes it does, but sometimes it takes 2, 3, 4 presses. Batteries are fine and it's done the same on another key that i've programmed to it. Anyone else had this issue?

I thought this was batteries even though I only changed them a couple of months back but the issue is the same with some brand new ones.

I'm worried in case one day it decides not to unlock at all!

Any advice gratefully received :)

All the best

i would try the simplest thing first - disconnect the car Battery for a few minutes just to reset things and see if it helps

Is it doing it at different locations? If just in one location then there may be something else operating on the same frequency which is causing interference.

My next door neighbour had a wireless front door bell. Sometimes the pushbutton would jam on, so that it would be transmitting all the time. Both cars we had on our drive would not lock/unlock when that happened. It was only by happy coincidence that we put two and two together. Car electrical systems can be interfered with by different frequencies at times. The notorious (but thankfully few) "sudden unassisted acceleration" events that some car owners have experienced is down to this , I'm sure. It's not all jammed carpets or old age, though some cases are no doubt.
