This is an aftermarket, new Transponder Key Blank for a 2001-2003 Toyota Highlander. This is a transponder key, which means your vehicle must be configured to recognize the new key. This procedure is often referred to as 'programming.' Sometimes you can use On Board Programming to configure your vehicle, but other times it requires a special tool to talk to your cars computer. Your Toyota dealership or local locksmith will have this tool. The On Board Programming instructions are found here: On Board Programming Instructions

Another solution is to have your working Toyota key cloned to a new key blank. We can provide this additional service at a greatly reduced price, but it does require shipping your working key to us to be cloned.
