Ball Coupler Lock - Square Edge Design

I’ve recently purchased my first travel trailer and when I got it home my first thought was “man this would be really easy to steal”.Not anymore!I’ve had zero worries about this trailer being stolen now that this beefy lock is installed.It’s spendy but the piece of mind is so worth the money. Highly recommend!

Need Help With Your Lock?

How do I choose the right lock for my trailer?

Each trailer type has a specific lock model for the best fit. Use our Lock Selector Tool on our website to find the best option for your needs.

Are AMP LOCK products weather-resistant?

Yes, our locks are designed to withstand extreme weather conditions, including rain, snow, and high temperatures, ensuring long-lasting performance.

Can I order multiple AMP LOCKs that use the same key?

Yes, you can order AMP LOCKs that use the same key by selecting the "Keyed alike" option during checkout. If you already own an AMP LOCK and need a new lock to match your existing key, select the "Keyed alike - Use existing key number" option and provide the key information found on your control card or key tag.

Can I order extra keys for my AMP LOCK?

Yes, additional keys can be ordered through our website. You will need your lock's unique key code to request a duplicate. Order additional keys.

My AMP LOCK won't unlock. What should I do?

  1. Verify your key: Ensure your key has "REAL" engraved on it.
  2. 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.
