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 (TOY51): 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.
