Alex was great! He was incredibly quick, reliable, and professional. I was locked out of my apartment and from the time I called to the time I was back inside, it took about 30 minutes. He responded quickly and handled everything efficiently. I really appreciated his help and would highly recommend Alex to anyone in need of a reliable locksmith!

Needed to change out two deadlocks after losing the keys. Call around after Googling and found Alex on my second call. This wasn’t an emergency but he came over within 2 hours and had the job completed in less than an hour. He is very personable and professional.

He was so helpful to me when I needed help with my van. We figured it out that the steering wheel lock was preventing me from turning the key and that I didn't need a locksmith. However, I really appreciated that he was not just going to come charge me. He was going to help me solve the problem whether or not it meant he made any money. The best kind of service.

My old front door lock finally gave up the ghost this afternoon. I needed to leave the house and realized I couldn’t lock the door. I called Ace and spoke with Alex, who informed me he could be here in 10-15 minutes! He quickly determined that the lock needed to be replaced and replaced it within minutes. It was surprisingly efficient service and Alex was friendly and professional. I will definitely call Ace if I ever need a locksmith again.
