'98 - '02 Isuzu Rodeo and Trooper and Honda Passport(with factory keyless entry) Instructions for programming. 1. Get in car and make sure all doors are unlocked. 2. Open driver's door and leave open. 3. Put key in ignition. 4. Turn key to 'on position' (dash lights on, but do not start) and back to 'off position' 3 times in 5 seconds or less. (you must turn the key very fast) 5. Close and open driver's door 2 times in 5 seconds or less. 6. Turn key to 'on position' and back to 'off position' 5 times in 5 seconds or less. (turn key very fast) 7. Close and open driver's door the doors should lock and unlock twice after this happens push the lock or unlock button on the remote, doors will lock and unlock. Push the lock or unlock button a second time and doors will lock and unlock again. You are finished! The above sequence erases all previous codes and adds the new code as #1. If you are adding a second remote, you should follow the same sequence with the exception of step 6; instead of turning the key to the 'on position' and back to the 'off position' 5 times in 5 seconds or less, do it 3 times in 5 seconds or less and then continue to step 7. ***Remember to turn the key to the on and off position very fast. This works! Follow directions EXACTLY. I had to try 3-4 times before getting it to work. I failed to go exactly by the instructions the first few times.

there should be a relay and a fuse for the locks and the windows

This is the key security system. Somehow youv'e set it off. Used the wrong key tried to open the door with the alarm on. Opened the door or trunk from the inside after locking it from the outside. If your the real owner of the car it'll be no problem to get it fixed. If you have the correct key lock the doors from the outside with the key and lock it twice ( the doors ( all of them ) should lock). Leave the car alone for a minute, maybe 5. Then unlock the door twice, all the doors should unlock the second time. Enter the car and start it with the key. If you with a remote door lock fob that can work too. If this fails then try a different door or even the trunk. Sometimes the driver doorlock switch wears out or gets ice in it and unlocking a different door or useing the remote can get you going again.

Insert key into door barrel or ignition lock and turn key, whilst doing this press the unlock/lock button, the led on the dash should flash to indicate this has initialised the key to the car, then remove key and test operation of remote. If this fails then a new remote plus coding to the car by your dealership is needed

To reset the alarm, you have to lock everything back up and then use the key to unlock the tailgate FIRST. After that, you can unlock any of the doors with the key without the security system locking everything off.

(Needless to say, I gained familiarity with this situation from personal experience!)
