Chubb AVA keys (often also branded Union) are funny-looking brass keys common in padlocks and nightlatches. They’re small, and the cuts are made at an unusual angle.
These keys are found in Union 1K42 padlocks, Union C-series ‘Conquest’ locks, Union 1K57 Hercules padlocks, and the Union 4L67E auto-deadlocking rimlock. They can be found up and down the UK and Ireland.
Most AVA keys don’t have AVA written on them. Sometimes they have a code on them starting with FB, e.g. FB23. Many have JMA CHU-4G, CHU-5G, Silca ACH or 5ACH4 written on.
We can make these keys for you from a few good photos of both sides of your key. All you need to do is to upload a couple of photos using the upload tool above, and we’ll do the rest.
