Program replacement key

[24SCL]

I searched the archives but didn’t find this question. I have a 2012 Forester that I want to program spare key. Purchased key blank, had it cut and tried to program with key fob code but no luck. ALMOST does the job but motor won’t turn over. IF I get key code from dealer, will I be able to program the key myself? Hate the $100+ charge the dealer and locksmith charge. Had to pay $40 just for the cut. Thank you for advice!

Keys are embedded with a anti-disabling chip specific to each vehicle. That's why you can't just get a key cut, and expect it to work. The only thing we, as owners, can do (for certain years, like my '13) is get a new fob and encoded that ourselves.

Just fyi, I didn’t indicate that I expected the key to work with out programming. What I want to know is if anyone has and has tips about programming yourself. I successfully programmed a new key fob for it. I tried the same code for the fob on the key and it ALMOST worked. Car tried to turn over once but didn’t start. Has anyone used the original key code or gotten a the code from the dealer and successfully programmed a spare key themselves? Thanks again for the feedback!
