Wire in a Ford PATS Transceiver F8SB-15607-AC Ignition Lock Cylinder and Key FOB Explorer

Ok I'll try my best to help you disconnect the battery cables //// take off the bottom plastic shroud on the steering column pull the key cylinder ////first of all the wire is plugged into the ignition key cylinder housing in the column not the transceiver and it's 1 wire with a brass tang that fits into the cylinder housing once it fits snug the chime will stop/// next you must make sure the transceiver is (a) plugged in correctly snug fit (b) that the transceivers pick up ring around the key cylinder is plugged in and mounted properly on the housing (c) that the antenna for the unit is in tight facing the right direction all wires should be checked for continuity and the plugs should be checked for a tight fit after doing so reconnect the battery cables when the alarm sounds if equipped use your key fob remote to take it out of theft mode /// I'm hoping that your key is not a cloned key and that you disconnected the battery cables at the start of this when you first tried to investigate the chime problem if not then you erased the transceiver from the system (maybe) do you have other keys to try that are original ones? The unit works by first the ring on the cylinder see's the key and tells the transceiver that it's there then the antenna is picking up the chip in the key and sending that information to the computer to tell it to start the car and everything in that system must be originally installed and programmed into the system for the pats (secure a lock) start sequence to complete also if the antenna is facing the wrong direction it cannot pick up the chip key it must be as close to the cylinder as possible in direction which if a programmed chip is put behind the gear shift on the column and a regular key is in the cylinder the car will start so the antenna is positioned so when the gear shift is in park it faces the cylinder as close as possible to get the signal completed I'm not there obviously and I don't know exactly what you did but I tried to think of everything I could to help you good luck stephen

You can't just change parts an expect it to work , software , modules won't let it work . You have to take it to the dealer or have a mobile lock smith fix it , reprogram it ETC...

Anti-Theft -Passive Anti-Theft System (PATS) The passive anti-theft system (PATS) contains the following components:

• theft indicator
• encoded ignition key
• transceiver module
• PATS control module (located behind the passenger side air bag module)
• powertrain control module (PCM)
• standard corporate protocol (SCP) communication network

There is no PATS override button. PATS is Passive Anti-Theft System. It is a transponder chip in the key, and a transceiver ring around the ignition lock cylinder. The Ring looks for the correct chip in a key in order to allow the vehicle to start. A bypass or override button in the vehicle completely advantage of having the chip system and would render is useless in entirety.

That box is for the anti-theft system , he changed the lock cylinder . You need new PATS keys . PATS - passive anti theft system .The transceiver module communicates with the encoded ignition key. This module is located behind the steering column shroud and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends the data to the instrument cluster.
And the dealer is the only one that can program the keys . or a mobile lock smith .

Hi Eileen , How do you know your having a anti-theft system problem ? Any lights flashing when you try to crank the vehicle ? The engine does not crank over ? If it is a anti-theft system problem ,disconnecting the battery is not going to do anything except lose some learned setting's in some control modules . There are a few thing's you can check but if none of these are the problem your going to have to have it towed to the dealer ! It'll need to be checked for DTC'S - diagnostic trouble codes !
PATS disables the vehicle from starting if there is:

• a damaged PATS key.
• a non-programmed PATS key.
• a non-PATS key (key has no electronics).
• damaged wiring.
• a damaged transceiver.

P1260 indicates that the Passive Anti Theft system (PATS) detected a "theft condition". This basically means an incorrect signal, or no signal at all was received from the chipped key. Brief overview: your ignition key has a chip in it called a transponder that is read by the PATS transceiver (mounted around the ignition cylinder housing behind the column shroud). The signal is then sent to the PATS control module, which communicates with the Powertrain Control Module (PCM) and enables the vehicle to start. Sorry for all the acronyms! When an incorrect signal is received, the PATS module then sends this message to the PCM which triggers the P1260 trouble code, resulting in a no start condition.

Possible causes are: an incorrect key being used, faulty key chip (transponder), wiring concerns between the transceiver module and PATS module, the transceiver module itself or internal PATS or PCM module concerns. The first thing to do in this instance is retrieve codes from the PATS module and diagnose these. Once the PATS issues have been resolved you can reset the P1260. Communication with the PATS module will likely need to be done at a Ford dealer. A few things to check first: make sure the correct key is being used, and if you have a second key, try that one as well. If one key starts it but not the other, you may have a faulty key. If both keys do not work, then it is not likely a key problem.

Honestly, we see very few problems with the keys themselves. Make sure no one has tampered with the steering column shroud as the transceiver module located behind it is fairly fragile. Lastly check for an aftermarket remote start system. These are a common cause of no start problems with PATS equipped vehicles. Some installers will remove the chip from your key and tape it to the column (under the shroud). This basically bypasses the system and allows it to be started without a chipped key. The problem is that the transponder removed from the key is not designed to be used in this way and can fail due to extreme temperature changes and, depending on mounting condition, excessive vibration and shock. Other installers use a "key box" installed under the dash, and these have been known to cause issues as well. If you suspect the concern to be related to a remote start it may not be a bad idea to have it checked or removed to complete diagnosis.

I hope this information has been helpful (remember to rate this).

theft light should be flashing when system is armed. It should reset itself. If on steady, you have a probelem. Try your other key first. This inof should help you. Report back if you still need help.

Anti-Theft —Passive The passive anti-theft system (PATS) contains the following components:

• theft indicator
• encoded ignition key
• PATS transceiver module
• powertrain control module (PCM)
• standard corporate protocol (SCP) communication network

--------------------------------------------------------------------------------
Principles of Operation
The PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code out of over 18 billion, billion combinations.
The passive anti-theft system (PATS), also known as SecuriLock ®, uses radio frequency identification technology to deter a driveaway theft. This system is known as Securilock® in North America, Safeguard® in the U.K., and PATS in Continental Europe. Passive means that it does not require any activity from the user.
The SecuriLock® System (PATS) is not compatible with aftermarket remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. If equipped the remote start system must be removed before investigation of PATS-related, no-start issues.
Each encoded ignition key must be programmed into the vehicle's powertrain electronic control (PCM) before it can be used to start the engine. There are special diagnostic repair procedures described in this section that must be carried out if a new encoded ignition key is necessary.
This system contains a new feature named Unlimited Key Mode. This feature allows a customer to program more than eight keys to the vehicle if they request it. Each vehicle in Unlimited Key Mode is set up with a special Unlimited Transponder Security Key. This allows all the customer vehicles to share the same keys, but no other keys from outside can be used to operate the vehicles. For an individual customer, any randomly selected Security Key is acceptable. Refer to Unlimited Key Mode Programming in Key Programming Switch State Control in this section.
The PATS transceiver module communicates with the encoded ignition key. The module is located behind the steering column shroud and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends data to the PCM.
The control functions are contained in the PCM. This module carries out all of the PATS functions, such as receiving the identification code from the encoded ignition key and controlling the engine enable. The PCM initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
All elements of the PATS must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle will not start.
The PATS uses a visual theft indicator. The indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS concern, this indicator will either flash rapidly or glow steadily when the ignition switch is turned to RUN or START. The PATS system also flashes the theft indicator every two seconds at ignition OFF to act as a visual deterrent.
The following will activate the PATS and will disable the vehicle from starting:

• incorrectly encoded ignition key
• damaged encoded ignition key
• unprogrammed key
• non-encoded key (key has no electronics)
• damaged wiring
• damaged transceiver
• damaged PCM
