Programming: This remote must be programmed and cut by a qualified locksmith or dealership. Note: 1.Our products will be carefully inspected to ensure they can work normally before delivery.2.Our products are aftermarket parts instead of original ones. They can work normally as long as the compatibility, part number, size or appearance are consistent with the original ones.3.Please make sure the remote programming can work to your vehicle before asking the locksmith to cut the key. Don't wait for him to cut the key and discover that it does not work, which may make a loss.4.If the locksmith declares that the key is purchased online or is not an original part, or other reasons to cause it can't work normally, and guides you to spend more money to buy in his store, maybe he wants to make more profits. I suggest you replace other locksmiths to program.
