I would look at the backside of the power door lock switch for corrosion on the contacts (pins) and also the harness wires for the connector. Maybe the switch itself is just going bad.Honestly sounds like you have a shorted power wire that is touching just right with the vibration of the car. Probably is why it happens when you are driving.
Good luck

What is the default anti-theft lock code for a 2000 Toyota Camry LE


Is your problem that the vehicle will not crank and has no power, or that the door lock remote is not working? Im not sure that I understand your question and dont want to give the wrong answer.
There are no "codes" persay for anything but radios as far as end user procedures go. Programming doors on a 2000 camry is...fun to say the least. the procedure is published all over the web and very weird, but thats what they designed..
Short version is, Doors all closed, Ebrake on, key in your hand you in the drivers seat. Insert key and do not turn, then remove again. Do this TWICE. Now key is out, within 45 seconds, pres the electric LOCK button on the door LOCK-RELEASE-UNLOCK-RELEASE and repeat 4 more times for a total of 5 cycles. After the 5th time is complete, open the door, then close the door. Then do the LOCK-RELEASE,UNLOCK-RELEASE thing another 5x. At the end of this the door locks SHOULD cycle by themselves twice, if they do not...cycle the ignition key on and off again. and see if they cycle. I=When they cycle trhat means its in learning mode! Press door both buttons on yor remote at the same time, then release. Then do the next remote the same way. That is how they designed field programming.

Lost remote and like to program new remote. HELP. 2000 prado vx.


1. Start with the following conditions: you are in the vehicle a. Key is out of the ignition
b. Drive door is open ( all other doors are closed)
c. Driver door is unlocked (other door locks don't matter)

2. Insert the key into the ignition (don't turn it) and pull it out.
3. Perform these steps within 40 seconds: a. Cycle the power locks 5 times. Use an even pace and try
to go relatively fast.
b. Close, then open the drivers door.
4. Perform these steps within 40 seconds: a. Cycle the power locks 5 times (same as before).
b. Turn the ignition to ON then back to OFF.
c. Turn the ignition to ON then back to OFF.
d. Remove the key from the ignition.

5. Within 3 seconds, the power door locks should cycle (automatically)
indicating successful entry into programming mode. Return to step 1
if the locks do not cycle at this point.

6. Perform these steps within 40 seconds: a. Press the LOCK and UNLOCK buttons on the transmitter
simultaneously for 1 second.
b. Immediately after letting go of the lock and unlock buttons,
press the lock button by itself and hold for 2 seconds.
Within 3 seconds, the door locks should cycle ( LOCK then
UNLOCK) once-- indicating successful programming. If
the door locks don't cycle, or cycle twice. Repeat steps
6a and 6b--this remote has not been accepted.
c. Repeat steps 6a and 6b for EACH transmitter that will
operate the vehicle. Including any old transmitters.

7. Close the driver door.
Good luck and hope this helps.

Power door lock sticks. sometimes unlocks,


make sure linkage is not sticking, if everything is free moving then i would say you might have a bad door lock actuator. good luck,

How to program a 2000 mustang keypad


  1. Insert a key in the ignition and turn from off to on eight times in rapid succession (within 10 seconds) with the eighth turn ending in the on position.
  2. The doors will lock/unlock to confirm that programming mode has been entered.
  3. Within 20 seconds, program a remote transmitter by pressing any button on a transmitter. The doors will lock/unlock to confirm that the remote transmitter has been programmed. (If more than 20 seconds pass before pressing a remote transmitter button, the programming mode will exit and the procedure will have to be repeated.)
  4. Repeat the previous step to program additional remote transmitters. The doors will lock/unlock to confirm that each remote transmitter has been programmed.
  5. When you have completed programming the remote transmitters, turn the ignition to off or wait 20 seconds. Again the doors will lock/unlock to confirm programming has been completed.

2000 Mercury Cougar Power door locks do not work on either door


Power door locks are on the same fuse as the alarm system. The fuse is located in the passenger compartment fuse panel under the steering wheel. There is a pull down lever that will release the fuse box. The fuse for the alarm system/locking system is #25. Yellow color and a 20 ampere rating.
