How do I replace fuse for remote keyless entry?

Hello Cathy

It does indeed have keyless entry. It needs reprogramming when you get a new remote. Also if you disconnect the battery. Usually a local car alarm fitting shop, or an auto-electrician will do it. Plus of course a Ford dealership.

radio fuse 10 amp - location , under hood fuse box . This fuse powers the remote control door lock receiver

Circuit Description
The remote control door lock receiver (RCDLR) communicates with the body control module (BCM) through the keyless entry serial data circuit.
When any button on the keyless entry transmitter is pressed, the transmitter sends a signal to the RCDLR.
The RCDLR sends either a lock or unlock request to the BCM, depending on which button is pressed on the transmitter.
The BCM receives the message and performs the appropriate function.

The Lock's lock from the door switches ? If they do it's not a fuse problem . Which of these does your vehicle have ?
Keyless Entry System Description and Operation (with Accessory 2 Way Remote)
Keyless Entry System Description and Operation (without Accessory 2 Way remote)

The keyless entry system is a vehicle entry device. The keyless entry system is used in conjunction with the body control module (BCM) to remotely activate certain vehicle features. Keyless entry will lock/unlock the doors/liftgate when a corresponding button on the keyless entry transmitter is pressed. This is accomplished by the transmitter sending a radio frequency to the remote control door lock receiver (RCDLR). The RCDLR interprets the signal and activates the requested function via a serial data message to the BCM. A low transmitter or vehicle battery or radio frequency (RF) interference from aftermarket devices, such as 2-way radios, power inverters, computers, etc., may cause a system malfunction. High RF traffic areas may also cause interference that could lead to a malfunction. Keyless entry allows you to operate the following components:
• Door locks
• Liftgate lock
• Vehicle locator/Panic alarm
• Illuminated entry lamps
• Remote vehicle start
The keyless entry system has the following components:
• Keyless entry transmitters
• Keyless entry antenna
• 2 Way Advanced Remote Start RCDLR
• BCM

Your best bet , take it to a GM dealer .

replace the fuse and see if that did it.

try looking for a fuse relay for the remote central locking in the fuse box

RFA / MOD fuse 10amp . location - insturment panel fuse box. Fuse Block - I/P
Right side of the I/P, behind the access panel
If the fuse is good your best bet would be to take it to a qualified repair shop , that doesn't mean the dealer . Lot of good independant repair shops around , just have to check the yellow pages.
Do you know what DTC'S are ? diagnostic trouble codes ! Not only the ones for the engine management system OBD 2 . There are also DTC'S for the remote keyless entry system , BCM - body control module. You need a factory or professional scan tool to view this codes

The remote control door lock receiver (RCDLR) communicates with the body control module (BCM) through the keyless entry serial data circuit. When any button on the keyless entry transmitter is pressed, the transmitter sends a signal to the RCDLR. The RCDLR sends a lock, unlock, or panic alarm request to the BCM, depending on which button is pressed on the transmitter. The BCM receives the message and performs the appropriate function. The BCM also uses the keyless entry serial data circuit in order to communicate with the RCDLR when programming transmitters. Do you know what serial data circuits are ?

This is what the factory manual said as to the location of power steering fluid reservoir ! Not much help , you would do better googling it.
The power steering fluid reservoir holds the power steering fluid and may be integral with the power steering pump or remotely located. The following locations are typical locations for the remote reservoir:
• Mounted to the front of the dash panel
• Mounted to the inner fender
• Mounted to a bracket on the engine

Try reprogramming the remotes. Here are the instructions for the procedure. Hope it helps. Cobra!
Programming NOTE: All keyless entry remote transmitters (15K601) must be programmed at the same time.
NOTE: To program (or reprogram) the keyless entry remote transmitters into the RAP module, perform the following steps:

1. Make sure that the anti-theft system is not armed or triggered.

1. Turn the ignition switch (11572) from OFF to RUN eight times within ten seconds, ending in RUN. If the RAP module has successfully entered program mode, it will lock and then unlock all doors.

1. Within 20 seconds, press any button on a keyless entry remote transmitter, and the doors will lock and then unlock to confirm that each keyless entry remote transmitter has been programmed. Repeat this step for each transmitter.

1. If the door locks do not respond for any keyless entry remote transmitter, wait several seconds and press the button again. If the door locks still fail to respond, refer to Inspection and Verification.

1. Turn the ignition switch to the OFF position, or wait up to 20 seconds after step 2, to exit program mode. If a keyless entry remote transmitter has been programmed (or reprogrammed), the RAP module will lock and unlock all doors one last time to confirm.

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

it could be a fuse or a relay, the system probably has both you should check them and replace if bad. if they are good your keyless entry receiver may be bad.

does the key pad light when you press a button at night? If yes, the fuse is ok.
Do you have the plastic card with the permanent code in your owner manual packet? If yes, tryit.
report back.

Keyless Entry The keyless entry keypad is hardwired to the GEM. The GEM interprets the inputs from the keyless entry keypad and then controls the associated operation. The keyless entry keypad will be illuminated for five seconds when any button is pressed. Additionally, it will request the illuminated entry feature to turn the courtesy lamps on. If a lock all doors code is entered, the illumination will turn off, as well as request the illuminated entry feature to turn off the courtesy lamps. When pressed, the keyless entry keypad supplies the ground signal to the GEM or the GEM receives a signal from the keyless entry remote transmitter. Then the GEM outputs a ground signal to the appropriate lock or unlock relay which supplies the power to the actuator to lock or unlocks all doors, including the luggage compartment. The keyless entry remote transmitter also unlocks the liftgate or activates the panic alarm by sending a signal to the GEM.
