Locked out, lost keys

[Classic Nut]

Bought a 1985 Carlton estate and within 15 minutes had locked car up, then lost keys. Can’t get key cut as need key number and it’s not written anywhere. Vauxhall can supply a key/keys but need key number.

can get auto electrician to re-key it, but it’s not cheap.

Any help greatly appreciated

auto-locksmith would be your best bet and may be able to cut keys for it
