Keyless entry remote suddenly stopped working. now i cannot get into the car, and I am 500 miles from home. could it be a fuse in the car, or the battery in the key fob?

replace the fuse and see if that did it.

This is common on the CLK 500, but usually its just that the remote control wears out. I have changed mine twice already in 70,000 miles. Buy a new remote key fob and it likely will solve your problems if a simple battery change did not do the job. Always try that first and use top grade batteries, not those from the dollar store, because they fail too soon.

It sure sounds like a fuse. You can check for proper voltage at the hot wire of the actuator while you try to pop it. I think you are overlooking the fuse. Make sure the actuator has a good ground as well.

should not be using fob buttons for entry or locking for emergency only .if keyless entry walk up to car with fob do not press any buttons see if door opens then walk away from car with fob about 20m then go back to car without fob and see if door locked if so all working fine .indicators will not flash if the above dont work take back to main dealer for diagnostics keys may need to be reprogrammed

Do you mean the remote fob or the key pad on the side of the car. Fob could be batteries.

First, Congratulations on a '05 with just 63k miles. The '05 Pilot was the penultimate in Honda's fleet to date.
Try removing the battery and using a pencil eraser, scrub the contacts holding the battery in place.

You should have it scaned to see if you have any codes. It has a RCDLR (remote control door lock reciever) this is the module that recieves the signal from the fobs. If it has a problem then the system will not work. If it has to be replaced then a dealer will have to program it for you. Good Luck

does trunk button work? panic button?
here's 2003 info:

• The doors do not lock/unlock using the remote transmitter

• Remote transmitter.
• Driver door module (DDM).

• Go To Pinpoint Test G .

SECTION 501-14: Handles, Locks, Latches and Entry Systems 2003 Town Car Workshop Manual
GENERAL PROCEDURES Remote Transmitter Programming

1. Cycle the ignition from OFF to RUN four times within three seconds. The locks will then lock and unlock, confirming that the program mode has been entered.

1. NOTE: When the first keyless entry remote transmitter is programmed, all other keyless entry remote transmitters are erased.
   Press any button on the transmitter to be programmed.

1. If additional keyless entry remote transmitters are to be programmed, repeat Step 2 within 7.5 seconds.

1. To exit program mode, turn the ignition to START or wait 7.5 seconds.

report back

if it was factory installed theres usually a fuse in the fuse panel whereever that may be...replace the fuse with the same voltage as the other one says. but if the fuse isn't in the fuse panel its most likely under the hood, to the right...hope this helps. =)

Driver door module is where to look also a broken or corroded wire and if you use your key to punch in the door code then the key pad has a hole in it or it just went bad it's not the remote control also check the master door lock switch for corrosion at the pins and the plugs same with the driver door module
