    As a driving instructor in the San Marcos area, I have referred over a hundred of my driving students and other friends to this awesome place. The reason is because they have the advanced technology to make functional and affordable key fobs for most vehicles. Most people who purchase used vehicles need a spare second or third vehicle key fob and this locksmith can do the job. In addition, they are extremely knowledgeable about lockouts and home lock issues and installation procedures.
    We have sought their help with these procedures as well.
    Day and night’s small staff is very helpful, professional and respond very quickly. A real gem of a much needed business.

    Lost my keys for my 2012 f250. When I called I got a message and hung up cause I was frustrated but, I immediately got a call back from Michelle and she walked me through the process and we shared a personal moment, which made me remember that my problem was not the worst case scenario. Her husband Chris came and handled my issue with professional precision and a great attitude. I will recommend these PEOPLE to everyone.
