My highlander 2008, the doors can be locked and open with key and remote but cannot open the trunk with key and remote


To make the rear door open, you have to hold the button for a while. If the battery is weak, that will drain the power and the door will not open. Try the other remote and see if it works. At that point, I would replace the batteries in both remotes anyway.
That would be the fastest and cheapest way to eliminate one possible problem.
If the inside open button works to open the door, I would say the mechanism is working fine and it is the batteries.
I had to replace the batteries in both my remotes at the 3 year mark. That should be about now, the second time, for yours.

How to re-start my car after anit theft light has come on?


you need a full charged battery or battery replaced [if battery bad and not holding charge] your remote key fob will not work if battery is dead or to weak to start car but key should be able to manually open drivers door --if its not an original key new cut or worn down [may have to jiggle in door ] your anti theft/security lock will come on when you use key in door than you have a few seconds after you open door to put key in ignition and turn to on position before alarm goes off but you need to get battery issue corrected first if key still doesnt work may need to have assistance [slimjim]lock to get in

2005 Dodge Dakota alarm and key pad trouble


No i do not think you have electrical problem, try this.

Car in Park
Key on
push and hold unlock on good remote for 5 to 10 seconds
while holding unlock, press and hold panic, then release together
Listen for chime
press and release any button on all remote to be programmed.

If this will not work you need to bring the Vin# and remote to a dealer for reprogramming.

Try this, it works on several 2002 models:


Step 1: Open drivers door and leave open.

Step 2: Lock and unlock the drivers door using the power door lock switch on the door.

Step 3: Insert key into the ignition.

Step 4: Turn key to on position and return to off position. (IMPORTANT - use ON position NOT ACC position). Do this 3 times within 10 seconds. Leave key in the ignition.

Step 5: Open and close the drivers door 3 times. (Door should be left open after this step).

Step 6: ECU should respond by locking and unlocking the doors.

Step 7: Press any button on remote #1. ECU responds by locking and unlocking the car doors.

Step 8: Press any button on remote #2 (etc.) Each time the ECU will respond by locking & unlocking the doors.

Step 9: Remove the key from the ignition and the ECU will respond a final time with a series of door locks and unlocks. You're done
