I have an older Nissan Altima that I bought used, and it only came with 1 proximity key fob. The buttons on it started cracking, so I was in dire need to get a replacement soon, or have an even more expensive proposition without a functioning fob.

The dealer wanted $250 for an additional programmed (and emergency key cut) fob. Yikes. So I checked with a couple of locksmiths. They charged $171 or so, and each additional fob they charged about $130. So better than the dealer.

Instead, I went to Amazon and Ebay. I got a brand new replacement fob for my car from Ebay for $24. I later found a programmer unit on Amazon (with another key fob) for $90 (plus tax). I successfully programmed to two key fobs in about 10 minutes time, and for about $115 and change.

I have a coworker who also has a Nissan Altima, and my programmer will work for his vehicle too. He just has to buy a fob (or 2), and he said he'd split the cost of the programmer with me. So, now it just got even cheaper.

The moral of the story is, there may be options for your vehicle too rather than just dealing with the racket.
