BOLT 7025285
Ford standard/key groove
Match the conventional Ford key profile. This is not the Ford side-cut version.
BOLT Coupler Pin Locks: Ford, GM & Ram Vehicle-Key Guide
These BOLT trailer locks use the mechanical key from a compatible vehicle, so the correct key profile matters just as much as the size of the coupler latch. All four models below are adjustable coupler pin locks, not full-coupler ball-and-clamp locks. Compare the exact key type and the latch opening before ordering.
Three checks for the correct BOLT lock
1. Identify your vehicle keyFord standard and Ford side-cut keys require different part numbers. GM centre-cut and Dodge/Jeep/Ram are separate key families too. Verify the mechanical key blade using BOLT's current vehicle application chart.
2. Measure the latch spanBOLT specifies an adjustable span from ½ to 3⅜ inches with ⅛-inch increments. This is the coupler's latch-pin span, not its 1⅞-, 2- or 2 5/16-inch trailer ball size.
3. Check the locking pinThe lock uses a stainless-steel pin, approximately 0.27 inch in diameter. Compare the coupler latch hole, surrounding clearance and original pin rather than assuming all latches accept this diameter.
First-key setup matters: BOLT's lock cylinder permanently learns the first compatible key used when operated according to its instructions. It cannot be reset for a different vehicle key later. Confirm the correct key blade before initial use.

The shared latch-pin adjustment does not make the vehicle-key versions interchangeable. Choose the specific part number for the keyway you actually have, including the separate Ford standard and Ford side-cut styles.

Common coupler pin lock questions
Does BOLT 7025285 fit the same key as 7025290?
No. 7025285 is BOLT's standard Ford key profile and 7025290 is its Ford side-cut profile. Compare the actual vehicle key and published keyway illustration before selecting a lock.
Can I use the lock with a push-button-start vehicle?
BOLT supports compatible mechanical emergency-key blades as well as conventional ignition keys. The correct blade and keyway still need to match the specific part number.
Can a BOLT lock be rekeyed after changing trucks?
No. BOLT states that the cylinder permanently learns the first key used. Select a new lock with the correct key profile after changing to an incompatible vehicle key.
Is this a full trailer coupler theft lock?
No. A coupler pin lock secures a suitable coupler latch. Full-coupler locks cover or clamp around an unhitched coupler and are a separate product type.
Does a 3⅜-inch maximum span mean it fits every trailer latch?
No. The coupler latch hole diameter, usable space, latch position and lock-body clearance also matter. Check the original hardware and installation before ordering.
