I bought an old '90s public payphone from eBay that uses an Abloy Profile lock cylinder, but the guy that sold it didn't have the key; I could buy one on eBay, but it would cost more than I paid for the phone, and I'd prefer to avoid drilling the lock both because it would damage the phone and because I'm not even sure I could drill it (the cylinder has an hardened steel anti-drill disc). There's plenty of pics of the key online (see for example https://www.ebay.it/itm/254869988287), so I was wondering if there's any way of extracting the bitting from them like you can do with normal pin tumbler keys. Forgive me if it's a stupid question but I don't know anything about the way these keys are cut and this was the only thing I could think of. My only other option would be to pick it but I've never picked a disc detainer and from what I understand picking one of those would be pretty hard.
Thanks in advance for any suggestions
