Ford Focus PATS Disable / Reset Service

If your Ford Focus will not start after a PCM/ECU replacement, the Passive Anti-Theft System (PATS) is often the cause. Our PATS disable and reset service permanently removes the immobilizer requirement from your PCM, allowing your Focus to start and run without needing programmed keys or a matched PATS module.

How PATS Works

Ford PCMs often include PATS capability, even if the vehicle was not originally equipped. Once a PCM has been “married” to a PATS system, it will always expect the immobilizer handshake before starting. Our PATS reset service clears this lock, restoring normal plug-and-play function.

Donor PCMs from PATS-equipped vehicles can cause no-start issues
PATS-cleared PCMs start with both security and non-security keys
Compatible with Ford Focus model years 2000 and newer

Security Light Woes

After PATS delete, the security light may remain illuminated on some Ford Focus dashboards. If this occurs, the only solution is to remove the bulb or LED from the cluster.

Plug-and-Play Installation

Most customers can install a PATS-cleared PCM with no additional programming. In rare cases, a global DTC clear may be required before the Focus will start.
