Secure Locking Mechanism

This coupler lock has a disc tumbler locking mechanism. Unlike locks that use vulnerable spring-loaded pins, this ultra-secure lock is bump-proof. The cylinder has a series of rotating discs that can be correctly lined up only when you turn the corresponding key. Two identical notched keys are included to operate the lock. Because these keys feature 1 of nearly a million possible key codes, it's extremely unlikely that another individual will have a key that can open this lock.

See what our Experts say about this AMPLock Trailer Tongue Lock

  • What is the Strongest Coupler Lock and Locking Pin That Will Fit My Square Coupler
    I do have a recommendation for a coupler lock for your square coupler. I recommend the Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # FA86-0015-318. I recommend the Fastway Universal Lock because it is made to fit various couplers, including square ones like yours. Also, the bolted lock is internal to prevent prying and the key mech is rounded to make it more difficullt to pick. Finally, it fits couplers up to 4" wide and the shackle is 6" long top to bottom,...

  • Best Trailer Coupler Lock For a Titan Zinc-Plated, Leverlock Coupler # T4845000
    The AMPLock Trailer Coupler Lock # AMP84FR is the most secure lock we carry for your Titan Zinc-Plated, Leverlock Coupler # T4845000. This lock uses a laser cut style key and the cast iron construction prevents damage from shock and cutting tools. The shape of the lock fits the front of your square style coupler to ensure it is secure as you do not have the lip profile that a traditional coupler lock like most locks are designed to secure.

  • Recommended Lock for Bulldog Collar-Lok Coupler
    For your trailer with a 2" Bulldog Collar-Lok coupler I recommend the EZ Lock Trailer Coupler Lock for 1-7/8", 2", 2-5/16" Bulldog Collar-Lok Couplers # BLTL-20-40D. The Amplock you referenced fits a different style of Bulldog coupler. The Blaylock EZ Lock is specifically designed for your coupler style. Once it is attached, the coupler will be inoperable providing you with the security you are looking for.
