Question:

I am trying to unlock the device so that I can remove it from my receiver but the key doesnt seem to want to turn so it will not unlock. Are there any tricks to unlocking the device. It is not corroded or anything.

After a long period in place a lock mechanism can stick and make it tough to get the key in it, or to get the inserted key to turn. There are a few suggestions I can offer to you to get your lock # 1480DAT open.

You can spray a bit of aerosol white lithium grease into the lock. Do not use powdered graphite as it will eventually harden. A small amount can also be applied to the key before it is inserted. The keys themselves sometimes will benefit from a bit of fine (500 grit) sandpaper rubbed on their surfaces. This will remove microscopic burrs that can cause sticking. Also, a good old-fashioned whack with a hammer still does it in certain cases, but as a last resort certainly, after you have tried the other remedies.
