I was recommended to Ryan from the guys at Ron Tire that had helped me with my ignition issue. The lock on the driver's side was broken and I thought I would spend the extra cash to get keyless entry (i.e. a car remote) vs buying a $50 lock and installing it myself.
I asked for a quote and was told $80 sans module and $150 if it needed it. I had heard from other mechanics that my car (Saturn 07) should not need a module, so I got excited about getting it cheap. The main issue was that the process itself takes about 2 hours, so I had to schedule a time where I could drop off the car and pick it up later (and get rides for each). They are open until 6pm on the weekday but they also had slots on Saturdays.
Make sure to make an appointment, because they will not likely help you without it. I came in and stuck around for a bit, enough to find out that my car WOULD need a module and I'd have to pay almost twice the price. I was not a happy camper, but I was also trustful that this wasn't the mechanic's fault and that it was all because of my car type. I coughed out the cash and my car was fixed. No complaints yet, its been working fine. I hope it continues to be that way (fingers crossed)
