What information is needed to get a key/fob made for the 2014 MDX if you lost/don't have all of the keys? How much do dealers normally charge and can any locksmith do it? What's the least expensive route. I saw some fob for about $50 on ebay but wondered if just buying a remote start kit would be more worthwhile for 2 sets.
Ouch. My understanding is the dealer has to do the fob programming. You can call the dealer to see if they willing to program a used fob purchased on Ebay. Some dealers will tell you reasons why they can't program used fob to make you to buy new fobs from them. If you have to buy new fobs, check online from one of discount stores to see if it's cheaper.
The blade (key) part of the fob can be cut buy a locksmith or a dealer. If you buy used fob from Ebay, most still have old already cut blade that was for the previous car, so you might still need to buy new uncut blades.
Also to consider is the fact that you don't have any working fob. Dealer has to do programming for both key all over again (more $). I am not sure if you even have to have your car towed to the dealer. If you just need to do one, the dealer can copy the programming from an existing fob over to the second fob.
