If the PATS programming function is available in the Service chapter, it is implemented for this model and must work in full. There are 2 types of secure access: coded and timed. Coded requires an incode generation by the outcode provided by vehicle. Timed access requires that operator has wait for some period of time usually 10 minutes with diagnostic tester connected. Some vehicles support only coded access, some only timed access, some support both. FORScan supports all of these options.
If both access types are available, FORScan asks user to select the preferred one. Module Initialization option available for some models may require special Dual coded access. Detailed information about. This is quite important option so we have decided to create a dedicated article to discuss it. In many cases PATS system is distributed, it means more than one module is involved in the protection.
Module Initialization function is designed to synchronize match these modules with each other. It should not be used during simple key programming except AU models. The inialization logic is model-specific, so it is always recommended to read information FORScan provides before start of the procedure same informaion is always available using Help item in the PATS programming menu :.
Most common usage — initialize when new fuel pump is installed. Erase all keys Single coded or timed access have to be obtained ii. Program at least 2 new keys iii. Do module initalization. If only FIP module is replaced, then steps i and ii are not necessary and only step iii have to be executed. If only PCM is replaced, the steps i and ii are not necessary, and only step iii have to be executed. Module initialization logic here depends on the model, so follow FORScan instructions and acknowledge the Help info as mentioned above.
Also, timed access to PATS is used for these models in majoirty of cases. These models have no dedicated functions for erase and program keys.
Programming is performed as a whole — keys are erased, then programmed. Module initialization is a part of this process and called automatically. Module initialization can be called separately to match BEM and PCM, for example if the match was lost for some reason or programming procedure somehow failed before the initialization was completed. Coded access is also not used here, similar to US market models.
Extended license viewtopic. PATS knows 2 master keys, but the owner has only 1 of them. The owner wants to erase the lost key from the PATS memory and program new one for this purpose a blank key is purchased. There is no way to delete a single key, only all known keys can be erased. So the user has to perform the operation in 2 steps: remove all keys known by PATS and program the old key and the new key.
Here we go:. Select the Ignition Keys Erase option. FORScan will read outcode and suggest you to generate an incode using the built-in generator:.
As a precautionary measure for all of the above procedures, you should wait at least one minute after you have performed this until you start your vehicle. This website uses cookies to improve your experience. We'll assume you're ok with this, but you can opt-out if you wish.

That stands for Passive Anti-Theft system. And here's the most important line right here. Security access will take 10 minutes.
So even on the Ford tool there is a minute delay in order to get into the security system. It gives us a whole bunch of different options on the screen.
And what that does is as long as there is one key programmed to the car, the customer who owns the car can actually program additional keys by using the procedure in the owner's manual. The next one is Erase All Keys. That's pretty self-explanatory. It'll take all the keys out of the memory. Next one tells you how many keys are actually programmed to the car. Looks like we've got five programmed to his car.
Next one is Program Additional Ignition key. That's where you're going to go in to program new keys. Unlimited Key Mode: it's going to have either a normal mode or an unlimited mode and in unlimited mode. You can program unlimited keys to the car. That [setting] will tell you whether or not that unlimited key mode is on or off.
Let's erase all the keys out of this car and reprogram the three new ones that we have. Very important messages come up on the screen. So read this message carefully: Keys may look identical, but can have different transponder chips.
