Hello,

Looking for suggestions. We have a 2004, ended up “misplacing” my main key fob and looking to replace this. Wanted to see what the best option is to purchase an OEM replacement part # 89994-50240 (other than ebay or amazon)? This is the SmartKey with the option to open the trunk vs the valet. I called the local dealer, was quoted $169 plus cost to program. I also spoke with my local mechanic and they mentioned beware of internet purchases that could potentially have issues with programming. Some of the other thread mentioned call the locksmith. What have you done to replace a lost SmartKey? Are there other options with all the same functions?

Thank you!

 

Did you just lose one of multiple keys? Or did you lose your only key?

I don't know about quality of aftermarket fobs, but as far as programming, you can purchase the TechStream software and an OBD II - USB cable for $15-$30 on ebay or amazon and program the key yourself within just a few minutes... as long as you still have at least one key. If you lost all keys to the car, I've heard that you'd have to replace the ECU and get keys with the new one since there's no way to 'figure out' what code is needed for the ECU.

 

I think the going eBay rate is $94 brand new? If you decide to try used, be sure that you see the trunk button labeled (if it isn't, it's a valet key).

I wasn't looking for the key itself but rather the end door, so I got one for $15. But it is a valet key so the insides also lacks the trunk.

 

Thanks for the suggestions. I still have the Valet Key, but you have to stick it in the ignition to start, it will not work within proximity of the car.
