The cost for a locksmith to come out is hilarious. There are a couple local ones here that survive on just the students locking their keys in their cars. I think they get like $75 a pop for each call I imagine there are dozens a day, mostly at the rec center. I've watched them struggle a couple of times, but most of the time they seem to be there under 10-15 minutes including paperwork etc.
Well, a tow is more, breaking your window is probably more and if you hire the wrong person to get you in your car, it will be more. The guys that know how to pop locks, impression keys and actually get you out of the predicament will probably be low end $75, depending on the city. You're paying for experience, not for their time.
And they're most likely not surviving on simply opening cars. They're also originating keys, which is going to be expensive but usually less than a dealership. Some guys are good enough that they can look at your key on the driver's seat, read the cuts and make you a key.
And AAA doesn't work on Lexus, Wodie? Couldn't be more false. If your technician calls the the dealership on a job site, they likely didn't know wtf they were doing in the first place.
On the remotes, don't let the battery get too low. You absolutely can lock your keys in the car with a Honda remote, or any other, if the battery isn't giving the proximity signal enough juice. Sadly, I learned this the hard way personally and did so on the 4th of July in Carolina Beach of all places. Yeah, check the battery.
