Specs At A Glance

Good To Know

Q: Does this assembly include the key? A: Key inclusion varies by listing, so check the product photos and details before ordering. If no key is shown, plan to have the cylinder keyed to match your vehicle.

Q: Will this fix a key that turns but will not start the engine? A: If the key turns freely and nothing happens, the electrical switch section is usually the failed part, and this combined assembly addresses that. Confirm the column and connector style match your truck before installing.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
