pkf3 wont program on 02 explorer

The LED on the bypasskit turns on like it should and then starts to flash. The light on the dash turns on and off normally and the bypass even blinks with the light on the dash like it should. I tried programming several times and 2 different ways, but it wont work. I am going to try another unit tomorrow, but I wanted to know if anyone knew why the LED would flash when the key was put in and the ignition on. Thanks.

Your RX and TX wires are reversed. Make sure that you have the right one on the right wire.Jeff

I tried reversing them reseting the unit and then the LED didn't do anything, so I assumed they were right the way I had them. Maybe I should try switching them again. Thanks

Insert key # 1 and turn to run but not start, count to 3 and remove key, insert key # 2 and do same, then try to remote start car with remote starter and 1st attempt will not start. Try to remote start again and it should work. This happens a lot in Ford's.The wire I'm test'n isn't doin' what it's supposed to be doin'... I am so glad I printed that tech sheet, with the wrong info.

Do it right the first time... or I might have to fix it for ya

PKF-3 MODULE PROGRAMMING Programming is similar to Ford additional key programming. IMPORTANT: TWO (2) VALID KEYS MAX 5 SECOND INTERVALS BETWEEN EACH STEP ARE NECESSARY TO PROGRAM MODULE. Insert the first valid key into ignition. Turn Ignition key to “OFF” position and remove. Insert the 2nd valid key into ignition. Turn Ignition key to “OFF” position and remove Temperarily connect the brown wire of module to ground. Then using a jumper wire apply power to the vehicle ignition wire. The LED on the PKF-3 module flash once then come on again for three seconds. The PKF-3 is now programmed. Connect the brown wire of the module to the remote car starter (-) negative out when running wire. (ground out when running)Jeff

Those are the two ways I tried. I tried each way several times. I reset the unit everytime. I think the unit must be bad. I don't understand why when I put the key in and turn it to on, the LED comes on solid for a couple seconds like it should but then starts to flash rapidly. I just installed bypass in a 03 Ranger an it worked like a champ with techman93's method of programming, and the manual showed velocity Motors method. But on that one the LED turned on then off like it should. Thanks guys

Anyone else know why the LED would flash after coming on solid instead of going out?

you sure you got the right bypass? might be a pkf1.

XK04 is DEI/Bypasskit bypass we use at our shopThe wire I'm test'n isn't doin' what it's supposed to be doin'... I am so glad I printed that tech sheet, with the wrong info.

I just tried a different unit with the same lot# and same version: H.3 S.5 The sticker reads PKF3 Ford/Mazda Transponder Interface: Encrypted PATS3 What is wierd is that the LED on this one acted differently than the other one and I used the same harness. The LED would turn on and just stay on intil a few seconds after I turned the Key off and sometimes it would act like the last unit and turn on for a cople seconds then start to flash rapidly. I think I am just going to have to wait for an XK04. my supplier was out of them. Thanks for your help everyone
