'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, and close all doors. 2. Open driver's door and leave open. 3. Put key in ignition. 4. Turn key from OFF/LOCK to ACC and back to OFF/LOCK 3 times in one second intervals. 5. Close and open driver's door 2 times in one second intervals (the door pin switch may be toggled 2 times instead.) 6. Turn key from OFF to ACC and back to OFF 5 times in one second intervals. 7. Close and open driver's door once (or toggle the door pin swith once) and the doors should lock and unlock twice 8. Push the lock button on the first remote you want to program and the doors will lock and unlock. Push the lock button a second time and doors will lock and unlock again. And then 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 ACC and back to the OFF 5 times in 5 seconds, do it 3 times in 3 seconds and then continue to step 7. If you use the toggle on the door instead of opening it and closing it, you can put your left hand on that toggle and your right hand on the key, which will help you with the speed at which this sequence needs to be completed. Also, practice a few times and remember 3 - 2 - 5 - 1 for the first remote and 3 - 2 - 3 - 1 for the second, third, and fourth remotes. If you miss any steps, start from the beginning.

you have to take it to the dealer
You will know that your Honda Passport has a keyless entry by the absence of a keyhole. There will also be numbers on the door for a lock combination.

Try this: Turn the ignition to RUN (do not start), press the unlock button on the keyless remote, ignition OFF. Repeat 2x. Turn the ignition to RUN, press the unlock button on the keyless remote twice, the power locks should cycle to indicate successful programming. Turn the ignition OFF and test remote.
Replaced the battery in the remote.
Its the same as honda civics. It a series of turning the ignition key off and on while pushing button on the remote. Im sure you can look that up as it's more common
I would try a clock repair shop.
All EX models have key less remote entry. It was a standard feature.
in nj parts and labor for a good system with alarm/remote start about 295.00 installed
Put in the key and start it, turn it off, and re-start it.
