Will one master key and one key fob key program tbem?

I purchased these keys only to find out the chip inside was wrong. Company doesn’t care what they send you. Had to pay regular price to have a locksmith fix them. As for buying an extra key to program. Yes, you need one original key to program a good second key. Be sure to purchase from a reputable company. I should not have purchased from this company.

How do i know how to program a key

For you to program the (PATS) key you need to have 2 keys that already start vehicle you cycle both original keys from OFF TO ON you dont have to start you need to do both original keys within a few seconds of each other then you cycle new keys OFF TO ON within a few seconds of each other if you dont have 2 old keys you will need to get a Dealer or Hardware store or Locksmith to program keys
