Will it fit my car?
Check the back of your current key: if it shows FCC ID N5F-ID21A, this is the right smart key. The number of buttons has to match too. You can also pick your car in the Make / Model / Year search at the top of the page.

Program and cut it
- Programming: A new key has to be programmed to your vehicle: by a locksmith, by the dealer, or with a key programmer such as the Autel IM508S, Autel IM608 Pro II or Xhorse VVDI Key Tool Plus. Check your tool's vehicle list for your exact model and year first.
- Cut the emergency key (HU100R): Condor XC-Mini Plus II, Dolphin XP-005 or Dolphin II XP-005L cut it by code; the Dolphin XP-007 copies it from your existing key.
