Identifying ignition key code?

[hopsedge]

Greetings all- Newbie here. My sole ignition key for a ‘67 SV Alpine is a Lucas 92204 key; those numbers are stamped on the key. There is nothing stamped on the bezel of the ignition plate on the dash itself. I would like to get a spare, but all the forum posts I can find and even the Triple-C web site refer to key codes and prefixes like FS, RM, FT, etc. How do I identify what kind of key I have? None of the key blanks on Triple-C today look like mine. Many thanks.

Here are some typical keys found with Sunbeams. The ones with the shape on the right are more common these days. BTW, ...sorry for the delay

I had à Keys made from a Renault and Volvo blank

Thanks, SPMDR. However, my key is not really like any of the ones in your photo. It’s closest to the one in the upper right corner, but my key is completely flat across the top (i.e. not gabled), & my key has two longitudinal grooves instead of only one.

A-ha! I think I’ve figured this out. I believe that my car must have had a replacement Lucas ignition switch barrel installed by a PO (Lucas #5436731). I’ve now found images online of the same little square key I have with similar 5-digit numbers engraved on them.
