Generally speaking, to replace a key FOB usually cost between $160-$450. It depends on a few factors:

First, the year, make and model of your vehicle – there are different types of key FOBs for different manufacturers and therefore the price varies a lot. Audi or BMW key FOB usually cost about $160, not including programming while Chevy or Ford key FOB usually cost somewhere between $60-$120.

A Locksmith usually charges for key FOB programming somewhere between $100-$200. At the dealer, you can expect to pay about 15% less but you will have to tow your car there.

Finally, Brand new, used or aftermarket key FOB – you would be surprised but there is a huge difference between brands and where you get your key FOB from. An automotive locksmith will probably sell you an aftermarket key(Strattec, Autozone, etc) which are usually of good quality.
