How To Program A Pats Key Ford
Many Ford trucks, vans and suvs use PATs (passive anti-theft) keys. These keys prevent someone from copying your key to a blank and using the blank. There is a small chip in the key which the vehicle must recognize before it will start. The PATs key is used on the following Ford family trucks.
- Insert an existing key into the ignition cylinder. Turn the ignition cylinder to ON (RUN) and back to OFF. Remove the existing key and, within 15 seconds, insert the new key and turn it to ON (RUN). The security light will light up for two seconds to indicate success in programming the key into the vehicle.
- . Look for fault codes in PATS.then The PATS function will store fault codes when the PCM records a P1260. Be certain of the vehicle model year. Use only parts & keys specified for the appropriate model year. Check to make sure the issue is not with multiple PATS keys, small electronic devices that can be used to.
Antitheft and Alarm Systems: Description and OperationANTI-THEFTThe passive anti-theft system (PATS) uses radio frequency identification technologyto deter a driveaway theft. Passive means that it does not require any activity fromthe user.The PATS uses a specially encoded ignition key. Each encoded ignition key contains apermanently installed electronic device called a transponder. Each transpondercontains a unique electronic identification code, with over 72 million billioncombinations.Each encoded ignition key must be programmed into the vehicle powertrain controlmodule (PCM) before it can be used to start the engine. There are special diagnosticprocedures that must be carried out if new encoded ignition keys are to beconfigured.The encoded key is larger than a traditional ignition key.
The key does not requirebatteries and should last the life of the vehicle.The transceiver module communicates with the encoded ignition key. This module islocated behind the steering column shroud and contains an antenna connected to asmall electronic module.
During each vehicle start sequence, the transceiver modulereads the encoded ignition key identification code and sends the data to the PCM.The control functions are contained in the PCM. This module carries out all of thePATS functions such as receiving the identification code from the encoded ignitionkey and controlling engine enable. The PCM initiates the key interrogation sequencewhen the vehicle ignition switch is turned to ON or START.The PATS function uses the PCM to enable or disable the engine. All elements of PATSmust be functional before the engine is allowed to start.
If any of the componentsare not working correctly, the vehicle will not start.PATS uses a visual theft indicator located on top of the instrument panel. Thisindicator will prove out for three seconds when the ignition switch is turned to ONor START under normal operation. If there is a PATS problem, this indicator willeither flash rapidly or glow steadily (for more than three seconds) when the ignitionswitch is turned to ON or START. PATS also 'flashes' the theft indicator every twoseconds at ignition OFF to act as a visual theft deterrent.The PATS is not compatible with aftermarket remote start systems, which allow thevehicle to be started from outside the vehicle. These systems may reduce the vehiclesecurity level, and also may cause no-start issues. Click to expand.Generally for a PATS vehicle you must have two other programmed PATS keys to be able to add more.
This applies if there are two or more key codes in the PATS memory. If there happen to only be one code in PATS memory, then you only need that one key. If the PATS memory was empty, then you can use any PATS key. Therefore it can't hurt to try to add a key with what you have, it just isn't likely that less than two keys are in PATS memory.The PATS can accept a total of eight key codes.If you have less than two PATS accepted keys, the only way to add more is to remove all key codes from the PATS, and start adding them again. That code erase procedure can only be done by a special Ford diagnostic tool, at the dealer. After they remove the codes, the PATS module will accept any keys with the simple procedure. It will accept the first key without any requirement.
Then it will accept the 2nd PATS key only after the 1st is applied in the ignition. After that you have to have two programmed PATS keys again like normal. I have one working key(A) and another new key(B) that has been cut already and will open the doors and unlock the ignition but will not start the car.1. Make sure you have both keys.(A&B)2. Turn on car (B) but don't start.
Watch 'theft' indicator untils it goes out.3. Turn off and repeat procedure with second key(A).4. After 'theft light goes out, insert new key and turn on. Wait until the theft indicator goes off and then turn off switch.6. Wait thirty seconds.
New key is now programmed into security module. Repeat for any other keys.Is this it?TIA, GWB. I was just trying to get the sequence down, I wasn't sure which key and when to use the original and the new. I bought 3 keys on ebay and will try one when I get them. It looks like I will need to get one programmed at the ford house and then I can program the other two myself.Incidentally: PATS uses a visual theft indicator located on top of the instrument panel. Where is this indicator?
I have the Theft light that flashes when I turn the key on, the air bag indicator, Over drive along the bottom of the cluster but I cannot locate another. The writeup distinctly says there is a visual theft indicator in addition the the Theft light at the bottom.Thanks. Sorry, I was alluding to the original posters comment: PATS uses a visual theft indicator located on top of the instrument panel. Thisindicator will prove out for three seconds when the ignition switch is turned to ONor START under normal operation.
If there is a PATS problem, this indicator willeither flash rapidly or glow steadily (for more than three seconds) when the ignitionswitch is turned to ON or START. PATS also 'flashes' the theft indicator every twoseconds at ignition OFF to act as a visual theft deterrent.I have the Theft indicator that flashes, but not 'the visual theft indicator located at the top of the instrument panel' Mine is a 99, maybe his reference is to a newer model. I have one working key(A) and another new key(B) that has been cut already and will open the doors and unlock the ignition but will not start the car.1.

New key is now programmed into security module. Repeat for any other keys.Is this it?TIA, GWB. You must have atleast 2 keys stored in the PATS memory inorder to program any keys without diagnostic equipment.If you have 2 keys programmed and wish to program more (up to 8 total) then insert the first programmed key, turn to on (do not crank) for 5 seconds, then turn off and remove.
Within 10 seconds, insert the second programmed key and turn to on (do not crank) for 5 seconds, then turn off and remove. Within 10 seconds, insert the unprogrammed key and turn to on for 5 seconds, then turn off. Repeat for any additional keys you wish to program. Verify all keys work.If you only have one working key, you must have diagnostic equipment to program anymore keys.
Most dealerships will charge appx.5 to 1.0 hour at the shop rate to program keys. If you are near me, look me up and I will do it for free.
B1213Less than 2 (or 3 if equipped w/Valet key) keys programmed to the system.B1232/B2103Transceiver internal antenna damaged. Replace transceiver.B1342ECU is defective (EEPROM in PCM is not working — replace PCM). The “Service Engine Soon” light is illuminated. (Investigate PCM system). There is no communications with PCM: PCM will always communicate on the diagnostic link regardless of theft status. (Investigate PCM system).
Engine stalls on road: Once the engine runs for one second, PATS CANNOT disable the engine. Running stalls are not PATS related. Remote Entry/Keyless Entry problems: PATS is completely separate from the Remote Entry/Keyless Entry. There is a no-crank problem on vehicles without PATS Starter disable. Check chart, on reverse side, for presence of Starter. PATS Theft Indicator flashes every 2 seconds at Ignition This is normal operation for PATS to act as a visual theft deterrent. See chart on reverse side for applicable system.
PATS Theft Indicator stays on for 2 or 3 seconds (depending on system type) at Ignition RUN or START and then off: This is normal operation for PATS proveout on all vehicles except LS and Thunderbird. Ke y Programming Using Diagnostic T oolsProcedure #11 key required.
