2004 Toyota Land Cruiser starts up but then dies. dealer says it's key issue?

Asked by Nov 29, 2016 at 01:41 PM about the 2004 Toyota Land Cruiser 4 Dr STD 4WD SUV

Question type: Maintenance & Repair

After a recent car wash our 2004 Toyota Land Cruiser would start up but
then die within 1-2 seconds. Both the check engine light and the battery
light came on.  We had it towed 5-6 hours later to the dealership. The tow
person said it started right up and he could drive it into the dealer. The
dealer looked at it and said it was a key issue and that the immobilizer was
bad. So we ordered a new key and immobilizer. The first few days after we
got it back from the dealer, I would have to start it 2-3 times before it would
stay running. It was fine until the next car wash, when it did exactly the
same thing. Drove it home from the car wash and after parking it in the
garage it would start up but then die 2 seconds later. Finally, after letting it
sit in the garage and trying to start it for 48 hours it stayed running enough
to drive it to back out to dealer. They still keep saying the computer says i
has to do with the key??? HELP!

I have a 2005 Land Cruiser, that has the same issue after running it through the car wash or after a rain storm. The issue seems to be connected with the security system and the dealer cannot find the culprit. I have had it with the dealer 3 times, they get it running, I run it through the car wash, the hazard lights come on and will not shut for about 3-4 hours and then the security system immobilizes the starting of the vehicle. Please, does anyone have any solutions???

The dealer found that our windshield was improperly installed and the water was leaking through the seal upon car wash onto the computer and triggering the security issue. Maybe check to see if you need a new windshield?
