There are locksmiths that actually specialize in the automotive field. I started specializing in auto locks and keys in 1980.
I am making a duplicate key, 05/09 Forester, for a used car dealer at this time.
I started the search for key data with my automotive lock supplier. There were 3 choices for the key until I gave them the VIN number, then 2 were eliminated. They called their contact at a dealership and got the correct key number.
My next Forester key replacement job will begin with a call to my local dealer for the factory key number. Then I will search key suppliers including; internet, locksmiths and dealers for the best price.
My shop has the capability of copying side milled keys. (Laser keys, two track, 4 track, etc.) It should be possible to get the code, (cutting information) from the local dealer for the legal owner of a vehicle. Ask about the price from the dealer, it may include the key being cut. Ask about the dealer cost to program the transponder as it may be comparable to a locksmith.
It is better to prepare for the worst. Whether you are buying a car new or used, it would be prudent to get codes and any key data available from your dealership.
There are crooked people that pretend to be automotive locksmiths that will promise you a key, overcharge you and give tons of excuses why the key won't work and why you can't get a refund so please be careful.
Basically you can get information all over the internet and if you have done some homework you will make an informed decision. Don't wait until you are put in a desperate position where you may have to pay hundreds of extra dollars for a key.
The combined cost of a duplicate key for a Forester, (the key, cutting, programming) will cost from $ 300.00 to $ 500.00 from a reputable locksmith.
