Note: 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 konw that it does not work, which may make a loss. If the locksmith declares that the key is purchased online or is not an originally part, or other reasons to cause it can't work normally, and guides you to buy in his store, maybe he wants to make more profits. I suggest you replace other locksmiths to program. How to Replace Battery?Take out the key and use the tip of the screwdriver as a tool to open the back case, and replace the same battery carefully. You can use a clean cloth to clean the battery in case some dushes existed.Package Included: 1 x Car Keyless Entry Remote (Battery Included) 1 x Key
