What customers say
"I cannot recommend Alec enough. My transit custom lock was not turning. I did not know Alec at this point and called another locksmith. To cut a long story short the other locksmith attempted a repair and then gave up, leaving me with a van I could no longer use. I called Alec who came out next day; he repaired the damage done by the other locksmith and custom made a replacement ignition barrel so one key still does the doors and the new ignition. I couldn't be more pleased. Price was very fair too!"
"Did the work at a 3rd of the price of the dealership and I'm sure to a higher quality, the work was quick and professional. Could not recommend more!"
"Absolutely spot on! After ringing about 15 different companies who said they couldn't help and one company even saying the series of my car doesn't exist I found smarttech who I contacted who could finally help! The next day he came out and I now have access and a new key to my car! Fast and efficient polite service! Highly recommend!!"
