Question:

Hi. I have lost my key to my gorilla trailer lock. The no. Is 350.054

asked by: Garyosmachenko

Expert Reply:

The 350.054 is the patent number for the Gorilla Guard Trailer Coupler Locks 2" # 63228 and 2-5/16" # 63227 and not the key number. You will need to have the key number off of the key to get a replacement from the manufacturer. If you do not have a key you will need to contact a lock smith to remove the lock and order a new lock for your coupler.

@CliffB if you have the key number from the lock core you can contact First Brands to see if they have a replacement key available. Otherwise, you will have to replace it with another like # 63227.

@DarrenE Unfortunately, we no longer offer keys for those. You'll have to reach out directly to the manufacturer and see if they can provide you with a replacement key.
