Mk2 Felicia 1.6 Ignition Barrel. Trying to Identify Part Number?

Hello,

I have a 1998 1.6 Glxi Felicia. I have been looking through the Online Parts Catalogue via Briskskoda ( Oemepc & Zap) to try and Identify Part number for an Ignition Barrel for the car. I am not having much luck, can't see it listed. Does anyone have any suggestions as anywhere else to look for the parts number for an ignition barrel? The car is my daily driver and currently without transport. A bit reluctant to try scrap yards as youngest part is going to be 20 years old. The key was starting to snag in the barrel, now won't turn at all. My local dealer can't confirm if they can get one or not, would have to come from Czech Republic. 

There are some  available on Ebay, but advert says for "models without immobilisor" my 1998 is more than likely to have an immobilisor.

The breakdown / recovery guy who came out to me said something along the lines of these keys available on ebay would work, if I took the transponder / chip out of old key and attached it to the new ignition barrel, and then just used the new blank key to start it. If the old key was still in the vicinity of the ignition it would start. Does that sound viable?

Sorry to be so vague, took 2 days recover the car, knackered. 

Thanks for any advice or suggestions.
