The Cargo Bunker Pack gives you a complete trailer-security setup: an AMPLock flat-lip coupler lock, 5/8" hitch lock, trailer latch lock, and two cargo-door locks. Together, they protect the trailer when it is parked, hitched, or loaded. The locks are keyed alike, so one key operates the full pack. Built with ductile iron and stainless steel components, each uses AMPLock's push-and-lock system and disc-lock cylinder to help resist picking, drilling, prying, and harsh weather. Made in Canada and backed by a 5-year warranty.

- Verify your key: Ensure your key has "REAL" engraved on it.
- Check how far the key turns:
- The key should turn ¾ of a turn to unlock.
- If it only turns ¼ of a turn, check if the key is damaged or incorrect.
- If the key turns between ¼ and ¾ of a turn, lubricate the lock with a non-silicone-based lubricant and use compressed air to remove debris.
- If the key turns more than ¾ of a turn or rotates fully, contact AMP LOCK or a locksmith, as the internal mechanism may be damaged.
