We are so grateful for your kind words. Thanks for sharing your review with us and the community.
I own a “difficult” vehicle and first shop could do it on my Range Rover sport. Guardian stepped in and referred me to another shop with electronics experts and got it done quickly and flawlessly.

We're happy to hear things ended up well. Thanks for taking the time to leave a review!
Everyone at Guardian located on Ocala on NE 17th Rd. were very friendly and helpful. The one lady that walked me through it made me feel very comfortable. I had a problem with the interlock device and Tim was kind enough to come to my home and help me out. I am very pleased with the service.

We're so glad to hear what we're doing right, thanks for taking the time to let us know!
My experience has been a great one working with Mrs. Tawanda Rozier getting my appointment set up. She was very helpful and when a possible issue came up she nipped it right in the bud & solved the problem. She is the reason I’m giving five stars!
