Securilock Keys

Anyone out there know how to reprogram the secureilock ignition keys on the 99 f-150? Rumour has it it is quite simple and ford dealers squeeze you for $50 to do 5 minutes of work. Any thoughts?

To program you need two previously programmed keys.
Insert first key turn ignition ON for at least one second. Turn off and remove. Within five seconds insert second key turn key ON for one second and no more than five seconds. Turn key off and remove. w
Within ten seconds insert unprogrammed key and turn ON for at least one second. The first time I programmed mine it took two tries before it took. Your owners manual should also explain these steps.

Nitro,

Does this reprogram the keys? Or does this just reissue the same program code of the origional keys? My desire is code jumping. I want to be able to periodically recode my key programs without having to go to the dealer. Thanks for the input!

This reissue's the same program. I would think it probably takes special equipment to reprogram to all new coded keys. Otherwise I could buy a key blank and recode and steel any vehicle with this system?

There are 72 quadrillion different codes available for those keys. Believe me, it only passes the original code to the new key.

I may be mistaken but I thought I heard that each vehicle can only program something like 6 or 7 keys and after that the dealer would have to reset some "magic box". I was also under the impression that each key had its own code and that the "magic box" logged which key was used to start the vehicle.

Yes, I was under the same impression, that each key had its own code, and you passed the code from the key to the computer... I, as well, have heard that you can program 6 or 7 keys to the computer... How will the computer know how many keys it has passed the code on to? Maybe someone could explain it better?

Securilock Keys

PATS = Passive Anti-Theft System, aka Securilock.

PATS keys contain a transponder that contains a unique electronic identification code. When you "program" a key, you're actually programming the PATS module or Hybrid Electronic Cluster (depending on the vehicle in question) to recognize the key. Most PATS systems will store up to 8 keys.

Here's a copy & paste of the Ford Service Manual "PATS Description and Operation" section:


Anti-Theft — PATS

The passive anti-theft system (PATS) contains the following components:

l theft indicator

l encoded ignition key

l transceiver module

l instrument cluster

l powertrain control module (PCM)

l standard corporate protocol (SCP) communication network

The PATS uses radio frequency identification technology to deter a driveaway theft. Passive means that it does not require any activity from the user. This system is known as SecuriLock® in North America, Safeguard® in the U.K. and PATS in continental Europe. This information can be found in owners literature.

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, with over 72 million billion combinations.

Each encoded ignition key must be programmed into the vehicle's instrument cluster (the instrument cluster is also known as a hybrid electronic cluster [HEC]), before it can be used to start the engine. There are special diagnostic procedures outlined in the workshop manual that must be carried out if new encoded ignition keys are to be installed.

The encoded key is larger than a traditional ignition key. The key does not require batteries and should last the life of the vehicle.

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.

The control functions are contained in the instrument cluster. This module carries out all of the PATS functions such as receiving the identification code from the encoded ignition key and controlling engine enable. The instrument cluster initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.

The PATS uses the PCM to enable or disable the engine. The instrument cluster communicates with the PCM over the SCP network in order to enable engine operation. The instrument cluster and the PCM use sophisticated messages in order to prevent a theft. The instrument cluster and the PCM share security data (when first installed together) that makes them a matched pair. After this security data sharing, these modules will not function in other vehicles. The shared PCM ID is remembered even if the battery is disconnected. The instrument cluster also stores the vehicle's key identification code even if the battery is disconnected. There are special diagnostic procedures outlined in this workshop manual that may be carried out if either a new instrument cluster or PCM needs to be installed.

All elements of 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.

PATS uses a visual theft indicator. This 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 problem, this indicator will either flash rapidly or glow steadily (for more than three seconds) when the ignition switch is turned to RUN or START. PATS also "blips" the theft indicator every two seconds at ignition OFF to act as a visual theft deterrent.

The 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. Remote start systems must be removed before investigation of PATS-related no-start issues.


As for key programming without special equipment...you can do it, provided you have two programmed keys (i.e. the original keys) and a new PATS key with the correct mechanical cut.

Here's the Ford procedure:




1. Insert the first programmed ignition key into the ignition lock cylinder and turn the ignition switch from OFF to RUN (maintain the ignition switch in RUN for one second).

2. Turn the ignition switch to OFF and remove the first key from the ignition lock cylinder.

3. Within five seconds of turning the ignition switch to OFF, insert the second programmed ignition key into the ignition lock cylinder and turn the ignition switch from OFF to RUN (maintain the ignition switch in RUN for one second).

4. Turn the ignition switch to OFF and remove the second key from the ignition lock cylinder.

5. Within 10 seconds of turning the ignition lock cylinder to OFF, insert the unprogrammed ignition key (new key) into the ignition lock cylinder and turn the ignition switch from OFF to RUN (maintain the ignition switch in RUN for 1 second).

6. If it is desired to program additional key(s), repeat the key programming procedure from the beginning.

Can someone please outline these steps. I have a theft recovery I'm trying to rebuild and can't get past this part.
Thanks

If you are changing the ECU or cluster a special diagnostics tool is required to program the system. Dealer only as far as I know.

So if I replace the PCM and the instrument cluster from the same vehicle it should work "if " I have the keys from the original vehicle?

Thanks
For all the help this has turned into a real project.

Post Securilock Keys

Look, let me explain this. I work for a company that makes part of this system, so I'll explain what is happening.

If you buy a new truck, you are issued 2 keys. These two keys were programmed into the PCM at the factory.

Each KEY has a code stored in a trnasponder chip in the key, and that code CANNOT be changed. When you are "programming keys" you are telling the PCM that the new key is "Good".

That is why you need both keys to program a new one. The assumption is that only the rightful owner would have access to both keys assigned to the vehicle.

When a new PCM is installed, it obviously does not know what two key codes were previously in the system, so it cannot be programmed as above and in the owner's manual for "additional" keys.

Since this is an anti-theft system, it was decided that without both keys, a special device (meaning a special program to tell the PCM it is OK to setup without the original keys) is needed if a new PCM is installed.

Most locksmiths have the keys. Usually cheaper than the dealer,but not much.

I got 2 keys for the wifey's Windstar for around $20 each if memory serves....

Programmed them my self, but the locksmith had the equipment to do the program too.
In fact he was setting up keys for a guy with a Ranger who'd lost one of his keys.

Not all locksmiths will have the programming equipment. The one I went to specializes in chip keys......
