You're bidding on a used good condition OEM 4 Button Ford smart key,the housing may show a bit wear & tear but no cracks,it comes with a free new key blank,it has been tested and shown in good working order,it's required to be programmed by the dealer or locksmith before use.Your original remote MUST has 4 buttons not 5,otherwise it won't work,the frequency is 315Mhz.
 
Thanks for watching.
