Trailer security hardware can be hard to identify from an old key or lock body. Check the stamped MPN and locate the part of the towing system it secures: the flat lip underneath the coupler, the coupler latch, or the tow vehicle's hitch receiver. These DeadBolt models cover three different arrangements.
Recognize what the lock actually secures
Engages the flat lip of a specified trigger-style trailer coupler, helping deter unauthorized coupling when parked.
Combines separate locking points for trailer storage and towing. Confirm the contents of the exact kit.
Pairs a receiver lock with a lever-style coupler latch lock, simplifying key management.
Match the model number and coupler geometry
Identify the lock style first, then compare the mounting surfaces and lock openings.
| Model | Lock style | Stated application | Critical fit check |
|---|---|---|---|
| TCL1-YL | Blockhead, yellow | 1⅞- and 2-in lip-engaging trigger couplers | Flat coupler lip, up to 3¾-in width |
| TCL3-AS | Blockhead, arctic silver | 2- and 2⁵⁄₁₆-in lip-engaging trigger couplers | Flat coupler lip, up to 4½-in width |
| TCL3-YL | Blockhead, yellow | 2- and 2⁵⁄₁₆-in lip-engaging trigger couplers | Flat coupler lip, up to 4½-in width |
| TSK3-AS | Tow & Stow lock kit | Selected 2- and 2⁵⁄₁₆-in flat-lip couplers | Kit with multiple lock positions; verify each point |
| RHC32 | Keyed-alike hitch and coupler set | 2-in receiver and lever-style coupler | ½-in coupler-lock opening |
| RHC33 | Keyed-alike hitch and coupler set | 2-in receiver and lever-style coupler | 2-in coupler-lock opening |
Inspect the coupler before replacing the lock
Photograph the original lock and check whether the coupler has a flat lower lip. Measure the lip width, identify the trigger-latch shape and inspect for any surge-brake actuator. For a receiver lock set, measure both the receiver opening and the coupler latch span.
The TCL3 series is designed for specified lip-engaging couplers; RHC32/RHC33 instead use a receiver lock plus a latch lock. The ½- and 2-inch values on RHC sets describe coupler latch openings, not the hitch ball.
