    The problem started as an intermiten problem. Replaced all key fob batteries.

    How can the controller be reprogrammed?

    Where is the body controller box located?

The 1st thing that happens before you unlock or lock the doors is the key FOB will send a program signal to the body controller to identify the radio frequency signal and digital code process it then activates the door actuator to move the latch up and down. In your case other areas such as windows/sunroof being affected-could possibly be that you have a power issue involving circuit breaker and the master switch. If it was mechanical I don't think it will affect all the doors-its unlocking and locking thru the use of the switch. To draw conclusion-I will say the communications between the key FOB and the Body Controller.

    You cannot program the controller by yourself, you will need a company technician. The program techniques are not availably publicly as it is a matter of safety.

Try putting the  key in and turn it to on so the ign light is on then press and hold both buttons on the fob for 5 seconds switch off and try it. This will work in 8/10 cases since the key is the boss here .
If not its an dealer with a Tech II scanner and you will need your 4 digit security code from Isuzu or the isuzu dealer will have it.

2000 Trooper LS. Why won't the ignition key unlock any of the doors? (the metal key part)



  • Some of the locks have been probably changed before.


  • Or you need to get original keys for truck, copies just get worn out by use.


Here a link to your SUV manufacturer:

Good Luck!

How do I know that the anti theft system in my 2001 Isuzu Rodeo is working ?


One way is to row your window down, step out of the vehicle, press lock on your key fob, reach inside the window, unlock door and open door. The alarm should go off.

Isuzu trooper 2001 battery replaced and key fob does not work with door locks but responds with 5 beeps when lock button is pushed. What might be the problem here. Thanks RJ


possibly it still thinks a door is open check out rear cargo door switch this is usually the culprit because its seperate from the rest of the doors. turn on rear cargo light to doors ,make sure it works then shut rear cargo door and see if light is still on. if light is still on theres your problem.
look at switch usually they get dammaged/distorted over time.

My isuzu trooper won't start Because an alarm


The ign key in the drivers door does the same job as the lost fob so the not starting is another problem .

If its a 3,0 diesel see my tips and try them if its the V6 petrol engine the qiuckest way is to have a dealer plug in a tech 2 as that will show whats up .
If you dont got a dealer come back on here !

THE BATTERIES WERE DEAD IN REMOTE FOR KEYLESS-ENTRY


This works on the older troopers min is a 95 giv it try
A-Open the driver’s door.
B-Insert key into ignition.
C-Turn the ignition switch to the ACC position and then to the LOCK position three times. (This step must be completed within 3 seconds – go as fast as you can, or the system will not enter the programming mode.)
D- Within 10 seconds, close and open the door two times.
E-Turn the ignition switch to the ACC position and then to the LOCK position three times (again, do this within 3 seconds.)
F-Within 10 seconds, close and open the door. Verify that the power door locks cycle once to confirm that the system is in programming mode.
G-Within 20 seconds, press the LOCK button on the transmitter you are programming. Verify that the door locks cycle once.
H-Within 20 seconds, press the UNLOCK button on the transmitter. Verify that the door locks cycle once to confirm that the system has accepted the transmitter’s code.
I-Repeat steps 7 and 8 for each transmitter to be added. Remove key from ignition.

How do i reset the factory alarm and door locks on 99 Isuzu Trooper?


Hi the alarm and locks dont need resetting they do themselves is it the remote locking fob thats at fault ?
If so put the key in and turn to ign on then press both buttons on the remote fob that normally does it if not its the isuzu dealer and tech II you need.
