Immobilizer/security indicator light flashes
2005 GX470.
After returning home my wife parked the GX470 in the garage. She returned 30 minutes later and noticed the headlights were on. She also noticed the immoblizer light was blinking.
We always keep the headlights in the "auto" position. Headlights staying on is a little strange. but I recall the lights staying on once or twice before. Immoblizer light flashing has never happened.
I inserted the key and turned to start the car and the light went out and the GX started fine. Once I remove the key, the light starts blinking again. I tried this with both keys to make sure it wasn't a transponder issue--all keys did the same as above.
I checked battery voltage--12.4v. Charging--13.6v at idle
Some light corrosion around the negative cable but not too bad. cleaned anyway
Wife did say she came out of work and noticed that two different car alarms were going off that were right next to her car. Possible kids messing around. Maybe our car was going off as well??!!
Any suggestions are greatly appreciated.
Thanks

I just picked up a used 07 GX this week. Wife went out to the garage and was playing with the door locks, nav/radio, lights etc and had it running. Now the security light is flashing all the time when the key is out and I'm 97% sure it wasn't flashing before. Everything appears to be working fine and the light goes out when the key is inserted and turned. Doesn't matter if the truck is locked or open, the light still flashes if the key is out of the ignition. The manual only indicates that there is a light, not how it behaves.
We can't figure out what she did to trigger it.

You could cancel that by just using the Flat key to cancel the activation of the Engine Immobilizer system. If you have made a duplicate key, you cannot cancel it, It can be done by the dealer itself.
The system get activated when the key is popped out. If the electronic code with the key does not correspond with the registered ID code. Here is how they look.
