As highlighted in practical demonstrations, tools like the Modis can effectively program keys for systems like Ford’s PATS (Passive Anti-Theft System) on models from the early 2000s and potentially some newer models depending on the specific security architecture.
The process typically involves connecting the Snap-on Modis to the vehicle’s OBDII port, navigating to the relevant system (e.g., Anti-Theft, Immobilizer, or PATS in Ford’s case), and following the on-screen prompts. As demonstrated, even with a tool like the Modis, security protocols are in place. For instance, the Ford PATS system requires a mandatory 10-minute wait time for security access, a built-in feature to deter unauthorized access.
Ford PATs Key Programming with Snap-on Modis: A Step-by-Step Example
To illustrate the key programming process, let’s revisit the example of programming Ford PATs keys using a Snap-on Modis. This provides a concrete understanding of how the tool functions in a real-world scenario and answers part of the question: “which car makes keys can a snap-on modis program?”. In this case, we know for certain it includes at least some Ford models.
Here’s a breakdown of the procedure as demonstrated using the Snap-on SOLUS Edge (similar software to Modis):
-
Vehicle Identification: Connect the Snap-on Modis to the vehicle’s OBDII port and perform a vehicle identification scan. This automatically identifies the vehicle’s make, model, and year, ensuring compatibility and correct system access. In the example, a 2007 Ford Taurus was identified.
-
Accessing the Anti-Theft System: Navigate through the Modis menu to locate the Anti-Theft PAT System. This is typically found under ‘Scanner’, then ‘Vehicle Systems’, and then selecting the relevant security or anti-theft module.
-
Security Access and Wait Time: Initiate ‘Security Access’ within the PATS menu. Be prepared for a mandatory wait time, often around 10 minutes, as part of the vehicle’s security protocol. This delay is a standard security measure, even with OEM tools, to prevent rapid unauthorized access.
-
Key Programming Options: Once security access is granted, the Snap-on Modis presents various key programming options. These typically include:
- Customer Spare Key Programming: Allows the vehicle owner to program additional keys using a specific in-car procedure (usually outlined in the owner’s manual), provided at least one key is already programmed.
- Erase All Keys: Clears all programmed keys from the system’s memory. This is often necessary when adding new keys or for security reasons.
- Program Additional Ignition Key: This is the primary function for adding new keys to the vehicle’s system.
- Key Count: Displays the number of keys currently programmed to the vehicle.
- Unlimited Key Mode (if applicable): Some systems might have a setting for unlimited key programming mode.
-
Erasing and Programming Keys: In the demonstration, the procedure involved erasing all existing keys and then programming three new keys. This highlights the importance of having at least two keys programmed after erasing, as some systems require a minimum number of keys to function.
-
Key Verification: After programming the new keys, it’s crucial to test each key to ensure it starts the vehicle and that the programming process was successful.
This Ford PATs example clearly illustrates how a Snap-on Modis can be used for key programming on certain car makes and models. However, it’s important to understand the broader compatibility and limitations.
