Ford F-150 - 1997-2003 :: 2002 - Key Less Entry Won't Working?
Apr 12, 2016
2002 F-150 XLT. Came with factory keyless entry. The remote type, not the keypad on the door.
A few months ago I noticed the remote would not unlock or lock the doors when I pressed the remote buttons. Usually after a few tries it would work though. Fast forward to Sunday and now the remote doesn't seem to work at all.
I changed the battery in the remote. No difference. Then I then reprogrammed the remote and it worked fine locking and unlocking the door. So I thought I was in the clear. Then this [Tuesday] morning I try hitting the button on the remote and sure enough it's not doing anything.
I'm really stumped what to do here. Could the receiver in the truck be bad? The truck isn't driven a whole lot. But the battery in the truck has enough juice to start the truck. So I don't think that's the problem. Any guesses?

If your truck came with the FOB to open the doors remote, but not the keypad on the door, you can add one. Originally the keypad was hard wired and was an expensive option. Several years later the newer keypads were RF signal just like the FOB. If you have or had FOB, then you have the keyless module on the truck (mounted to firewall infront of the emergency brake).. All you have to do is buy the newer style RF keypad, stick it to the door, and program like the FOB. I just did this on a 2002 F150.

My entry pad on the outside of the drivers door stopped working on my 2002 Explorer. Not only does it not open the doors but they don't light up when push the buttons. I looked in the owners manuel for a fuse related to this but did not see one. Which fuse the number pad is controlled by?

I have an '02 F150 Lariat CC 5.4L. The truck is new to me and neither the cruise control nor the horn works. i have checked all (known) fuses and relays. I have tried the cc diagnostic, and the dash light DOES NOT illuminate. Should I assume that the dash light is not burned out? Is there a way to test the clock spring connections for continuity? and how do I access the connection
i checked the cc brake pressure switch and have continuity there.

Over the last few days I have read several threads about heaters not working and blend door replacement. My '02 4.6 F-150 has 250k+ miles and I've always done regular maintenance on it. With the cold front moving in I've noticed that the heater is not blowing hot air. I flushed the radiator and flushed the heater core several times to make sure the core was not clogged. I also replaced the upper radiator hose because of the "crunchy" sound when squeezed. I also replaced the thermostat. Still, the heater is not blowing hot. I assume like many others that the blend door needs to be replaced. My question is do I need to replace the door only or the door and the motor (actuator)? I guess I need to test the motor before buying a new one. I saw a video where you remove all the components on the transmission hump and can actually stick you finger in the motor opening to see if the shaft has come apart.

I have a 2002 f150 supercrew, 4wd. The power door locks stopped working the other day and I am trying to fix it. So far I have checked the fuse in the power distribution box, good. I have checked the wires from the doors to the cab along the door sills to the rear doors , all good. I did find a couple of iffy grounds on the left kick panel and cleaned and repaired them. I am having a heck of a time finding the group of relays that control the lock and unlock functions. Remember , I have no power lock function at all. I would swear its not getting power to the relays but until I find them , I just don't know. Where they are supposed to be?

What would be involved with removing the keyless entry system on my '02 F150 XLT so that I can install it into my '97 Explorer that I am fixing up. Is it integrated into the main computer or is it a totally separate system? If so where is it located?
The Expo already has power locks just not keyless (or at least I never received the key fob for it when I bought it) I have shaved the door lock cylinders and am fabricating handles to be hidden in the window moldings.

I have a 2002 F150 FX4 Lariat, and last week while driving at night with the light switch turned to auto lamp the lights suddenly started turning on and off rapidly and there was a clicking noise, which I assume was a relay cutting out. I turned the headlamp switch to the on position and the lights stayed on. When I got home the lights would not turn off, and when I turned it to autolamp the blinking started again, but in any other position the lights stayed on. I had to unhook the battery. I then purchased a new headlamp switch and my ford mechanic buddy installed it, but now the autolamp feature will not work. Is there a relay that may have got cooked?

I have had my 2001 F150 Supercrew for about six months. After yesterday's rain, I noticed there is now water dripping inside from around the passenger side entry assist hand. I opened the sunroof/moonroof but didn't see anything obvious there.

I am having trouble with all sorts of functions on my 2002 F150 4x4, 4wd not working, cluster module illumination not working, horn not working, reving up and down at idle and sometimes dyin, cruise control quit working. I have been reading it is the GEM module that causes these issues. My question is I ordered a new one from Ford, when it arrives I was told I can just install it and It should be pre programmed. but one ford house tells me that they have to install it and program it. Which it right? I have seen several sites on u tube where people replace the module and then start their truck right up without any issue.

I have an 01 F150 SuperCrew with factory keyless entry fobs. I would like to be able to leave my truck running, take the keyless entry fob with me, and then lock the doors. Currently, the keyless entry fobs are disabled when the truck is running and I'd be locked out of the truck. I've had newer Fords that would allow the fobs to stay active with the vehicle running. Do this can be programmed into the truck?

I have a 2003 Camry I4. My RKE stopped working. First I checked the battery in the remote, it reads 3v like it should. I searched and found how to reprogram the the receiver, so I tried that. I did the door and key dance and got to where when you pull the key out and the door locks lock then unlock. I try pushing the lock and unlock button, then just the lock button as per the instructions and I get nothing. Supposed to get one cycle of the locks if it works and tow cycles if it doesn't. I get neither of those, nothing happens. So I buy a new remote off of eBay (brand new, never used, OEM remote). I try the reprogram door dance again and get the same results. The battery in the new one reads 3v like it should as well. So I go off to a junk yard to replace the receiver door controller, I found one and replaced it and I get the same exact results.

Well now I have to replace the multi function switch due to moving my steering wheel and the headlights sometimes working and turning signals not working. I saw a great video on youtube about changing a Multi Function Switch and it shows where the air bag needs to be removed. I was hoping that since my truck is an older 1997 F250 LD I wouldn't have to remove the airbag. Is there a way to do this w/out messing with the airbag on the 1997?

My remote start/entry on my 2013 F250 won't work outside of 25 or 30 ft from the vehicle. On my 2011 it would work close to 100 yds away. My dealer has no idea why. And yes, I changed the batteries

The AC on my 2001 F150 didn't work correctly so I bought a gauge and a bottle of AC juice and decided to charge the system. The AC starts out cold and turns warm. I put the gauge on the system and the needle goes to the red portion of the gauge. The AC will turn warm.
Is there a relay switch that quits functioning? Is there a code I could look at to determine the problem?

Have a 1999 F-150 work truck that I bought. Of course the blinker aren't working. Flashers, wipers, H/L's all work just fine. Nothing for blinkers outside or dash indicators, either side.
Checked fuses, every time I try something and are good.
MFS. Took old one apart cleaned no change. Bought new switch no change. Have power in harness up to switch in 2 spots.
Wiring. Noticed while replacing MFS the couple wires loose on the back of harness plug. Cleaned and pushed them back into block. Making sure they are fully seated to make contact with MFS. No change. Bent contacts on switch a little for tighter connection. No change.
Replaced relay/flashers. No change. So obviously I'm overlooking something. The truck is a western truck. Hasn't been modified or messed with. Nice clean original, heck only 61000 miles. Wiring under dash looks untouched. Still has the factory AM/FM only radio.

I have a 2002 f150 super crew, 5.4l and 4wd. The low tone horn is not working and I am having trouble locating it. Where do you suppose Ford has hid it?
