Napier trigger locks

[Poh]

I have just bought 2 Napier trigger locks. Gave them both a try and noticed that they both have the same key. Now I know there are only so many pin and height combinations for a 5 lever lock, but what are the chances? Or……do Napier use the same locks on all of there trigger locks?
Anyone ever tried their key on another lock?

Was staying in a hotel up the west coast and used one of these as extra security, all dandy until I was running late and ended up pulling the file out of the slip to shoot a nice stag and … yup trigger lock was still on the rifle.
As stated anything can remove - no key required. Visual deterrent only.
