Trunk, door, and glove box key question

[111]

I received one set of keys with the car, and assumed the smaller non ignition key was for the trunk and/or glove box. As it turns out the key does not seem to work for either, and until I get a spare ignition key, I am reluctant to try it in the door, much less the trunk.
So what keys work on which parts of the car? I've had cars where the ignition keys fits everything, but I do not suspect that is the case with MGB's.

Any advice/info will be appreciated.

The big key with the rubber head is your ignition key.

The large metal key with no "padding" is your glove box key.

The small metal key is for the doors and the bootlid.

Disclaimer....the above is correct IF they are the keys that were dispatched with your MGB from Abingdon.
