I needed a forklift part and wasn’t sure which one fit. They asked for the model and serial number, got back to me quickly, and made sure I ordered the right one. Really helpful.

Frequently Asked Questions

Q: Will this ignition switch work if my truck has a Passlock anti-theft system? A: The lock cylinder can be installed, but the Passlock sensor may require a relearn procedure. Check your vehicle's security system requirements before installation.

Q: Do these lock cylinders come keyed alike? A: Yes, all cylinders are keyed alike and include two identical keys so a single key operates the ignition and both front doors.
