EDIT: Ali, the manager at Marathon Locksmith, reached out and followed up with me. Apologized for the experience and processed a partial refund. I appreciate the follow up and action taken. Changing from 1 star to 3 stars for the amendments.
Original Review: I am trying to figure out how this business has 5 stars all around. They charged me $500 for the following: I called because of being locked out of my car at the airport, someone came in a car that had no signs of the business, he then helped me open the car door essentially by inflating a cuff to open the door and insert a stick to flip the lock internally. Not a single look at the keyhole, no keys were produced, nothing. Just for opening the door. Then asked me to pay via Zelle as friends and family because otherwise payment would be retained for review for them. I had to ask for an invoice, which I’ll attach and does not even say the business name. It was also $500 because that was the Zelle limit, they had charged me $520. I acknowledge I could have said no to the service, but I also already had them there and I’m desperate to go home, so that I’ll take accountability for. However, $500 for forcing my door open and no other service? That is absolute robbery.
