Keying to Previous Order:

To Key your lock order to the same as your previous lock orders, you must choose Keyed Alike and write, "Please Key to Previous Order RC########" (where ######## is your 8 digit sales Order Number of your first lock order) in the Customer Msg box.

Note: Always refer back to your first lock order so all new orders will be keyed to that first order. We will try to check that your keying instructions are correct, but this is only a courtesy. You are still responsible. DO NOT USE YOUR KEY CODE.

The Trailer Door Lock is a cast steel barrier box with a removable, reusable, keyed locking device that covers and protects the hasp of most tractor trailers with swing-out doors. The lock is nearly impenetrable and also the interior is completely hidden from thieves. It also comes with a 12" cable to tether the lock to the Trailer.

The TL-10 cap protects the key hole and disks from elements that will travel upward and into the lock. This feature is especially helpful for those that travel through freezing weather. For fleets, the TL-10 Cast Steel Barrier Box can be keyed individually or alike with or without a master key.

Note: The TL-10 does NOT fit Intermodal Shipping Containers, nor smaller Travel & Cargo Trailers. It will also NOT fit the Utility Brand Trailers. You will need the IR-20 for Intermodal Shipping Container Security.

War-Lok Locks are Pick Resistant, Drill Resistant, Bump Key Proof and Key Duplication is virtually Impossible.
