Starting with the proper blank is "KEY" ( sorry ) also finding good key-cutters is getting rarer. There's a place near me that gets it right 99 % of the time but they don't cut complicated keys. Other places have messed up & given me non-working keys, so make sure they stamp the key or verbally back up their work, they might not agree to this with a blank you provide however. The good thing is Porsche keys look fairly simple to cut .
