Hi all I'm from the UK and looking for a little advice. I bought a sx4 over the weekend, it had keyless entry as the key column has the key almost built in and the doors have those little rubber buttons on. I only know this over researching it as they only had the master key. So I've rung around including the dealer and they want around £180-£200. My question is couldn't I buy a new proximity fob and code it myself to reduce the cost or is this a specialist ares only. Thanks!!
