Lost Es350 Transponder

[AMES350]

I lost one of my black transponders (the one that attaches to the actual key). I have the key but don't know where did I put the transponder. Anybody know how much a transponder will cost?

www.sewellpartsonline.com is probably the best source, http://lexus.sewellparts.com/accessories-catalog/Keys/ES350-2012/2706.html

You can log in and tell them you're an LOC member and they'll give you a discount.

You can try looking on ebay. Wherever you buy it, you’ll need it programmed to your car.

Be careful on eBay, if they're not for the right model they wont work.
