2022 Five Top Car Key Programmers

Car key programmers are an important part of any mechanic’s tool set, whether you’re a professional or a DIY repairman. But, there are a lot of key programmer options on the market. Some key programmers are single-purpose, focused exclusively on generating new keys. Others include a range of diagnostic and service functions so they’re helpful all-in-one tools for any garage.

While keys can be obtained from a locksmith, mechanic, or dealership, they will need to be programmed either way. Having one in your repair kit can help save you the time and hassle of getting a new key from a locksmith if yours is lost or broken.
