My key less entry is not locking/unlocking my car doors. I discover the problem this morning when I tried to open my car. I had to put the key in the lock and open it that way. It also doesn't making the beeping noise either when I press the key less entry. When I use the inside lock/unlock it only works for my passenger side door. It won't lock my driver side door. I physically have to close my door and put my key in the key hole and turn to lock. Help?

It depends on your vehicle what is the year make and model? on some vehicles you try unlocking and unlocking your door with the key wile the alarm activated also try opening the ignition switch and if you have key less entry unlock and lock the doors.

THAT really sounds like someone is pranking you by swapping your car for another car just like it.

dead battery in fob or need to reprogram fob or system failure

Try pressing the unlock button twice

Try this please!
'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.

You will need to try reprogramming the remote 1st, below is the complete procedure. If the reprogram doesn't restore function then you will need the dealer to test the keyless entry system, you may have a bad module or remote (only applies if both remotes don't work).

Program your factory keyless entry functions
For 2001+ Tacomas equipped with a factory alarm or keyless entry, here are some programming options that allow you to adjust the way your locks work.
The first programming option allows you to set the entry unlock to: (A) unlock the driver door with one push, and the remaining doors with a second push OR (B) unlock all of the doors with a single push.

• Open the driver's door. Remove the key from the ignition switch.
  
• (Complete these steps within 40 seconds)
  
  1. Insert the key into and remove it from the ignition switch 2 times.
     (IN - OUT - IN - OUT)
     
  2. Close, then open the driver's door 2 times.
     (SHUT - OPEN - SHUT - OPEN)
     
  3. Insert the key into and remove it from the ignition switch 1 time.
     (IN - OUT)
     
  4. Close, then open the driver's door 2 times.
     (SHUT - OPEN - SHUT - OPEN)
     
  5. Insert the key into the ignition switch and leave it in.
     
  6. Close the driver's door.
     
  7. Turn the key from LOCK to ON 4 times, ending at LOCK
     (LOCK - ON - LOCK - ON - LOCK - ON - LOCK - ON - LOCK)
     
  8. Wait for the locks to stop, then remove the key from the ignition switch.
     
• On the key fob, press and release both LOCK and UNLOCK buttons at the same time.
  
  1. [For all doors unlock] press and release the UNLOCK button.
     
  2. [For driver door unlock] press and release the LOCK button.
     
• Open the driver's door. The programming is complete. If programming did not occur, start over.

Lock all the doors from the inside (with all the doors closed), unlock your driver's door by manually lifting the lock, then press it back down after you are out - this will prevent the alarm from sounding when you use the key to unlock the door.
