you don't have to go to a dealer.
buy a 1j0959753ct remote off of ebay. New or used, it's up to you. Then if you only have 1 key at the moment but you're wanting 2 keys make sure you buy a remote that has a new blade & transponder, the used remote part can be programmed with no probs
Personally i'd just buy 1 of these

Once you have a remote get the blade cut & if you don't have vag-tacho or vag-com etc find somebody near you on the forum that will program the transponder & remote to your car.
Or, if you just have 1 key & you're happy just having 1 key then you can transfer the transponder from your original key to your new remote, then get the blade cut.
There is a procedure where if you have 2 keys you can program the remote yourself. I found it a bit hit & miss. Although i have all the proper gear for key programming anyways so no need to fart about messing with 2 keys etc
oh & as a
guide, in case you phone around anywhere, i charge £90 to supply, cut & program most VAG keys within a 10 mile radius. The only ones that i charge more for are the newer CANBUS keys that need precoded keys before they can be adapted to the car. Not that i'm putting myself forward because i'm miles away! lol
