What vehicle years does this latch fit?
▾
The Labwork Front Left Driver's Door Latch Lock is engineered for Ford F-150 models from the 2009 through 2014 model years that are equipped with power-lock doors. It also aligns with the part numbers used on Mazda Tribute (2008-2011) and other similar trucks, making it a versatile replacement for a range of late-model pickups.
Does the latch include any hardware?
▾
The latch arrives as a complete unit ready for installation, but it does not include the mounting bolts, clips, or the interior door panel hardware that may have been removed during removal. Most vehicles retain the original fasteners, so you can reuse them, or source standard bolts from an auto parts store if needed.
How difficult is the installation?
▾
The installation is rated as moderate difficulty. You will need to remove the interior door panel, disconnect the power-lock connector, and bolt the new latch into place using basic hand tools such as a socket set and screwdrivers. Most DIYers with a few hours of experience can complete the job in under two hours.
Is this latch compatible with power-lock systems?
▾
Yes, the Labwork latch is fully compatible with factory power-lock systems. It matches the OEM part number 9L3Z-5421813-A, ensuring that the electronic lock actuator communicates correctly with the door latch, restoring the automatic lock and unlock functions that are standard on equipped F-150 models.
Can I use this latch on a vehicle without power locks?
▾
The latch is designed for vehicles equipped with power-lock doors, so it will function mechanically on a non-powered door but will not provide electronic locking or remote-unlock features. For vehicles lacking a power-lock system, a standard manual latch may be a more appropriate choice.
