its probably a 455khz version E, these are found in analogue am

I've seen 455kHz resonators in remotes before, but I'm pretty sure
I've seen other frequencies too. Thanks for the suggestion. I'll give
it a try unless someone can positively tell me that it's another
frequency.

Yes, I have no idea what that one uses, but most definitely there
is not one frequency used for every remote.

Not one frequency, necessarily; but usually only a very few resonators. The
last time I had one which was (physically) broken, I pulled another from the
first nondescript remote I found in the junk box, and it worked fine.

Remember, many frequencies can be synthesized from one crystal. Try one out
of a junk remote and see if it works...can't hurt.
