key fob for a 1984 90

I have a great SWB 1984 2.25 90.
One of the ignition keys is broken out of the original fob c/w light. Any tips on replacement fobs that will fit this key? or replacement keys to fit the fob?

I know about express keys but what i am looking for here are original key fobs that will fit this original key.

btw Expresskeys have sent me a key that did not look the same nor did it work. anybody else had a problem?
thanks

i dont think you can put yr exeisting key into a new fob tho
