That's right! Summer is in full swing and so are the scammers.
1-Make sure you ask for their ID and license number.
2-Never fall for starting at prices of $15, $19, $25 etc... more than likely those are scammers.
3-Don't fall for scare tactics either. If you have not agreed on a price and they say you owe them a trip charge and they say they will call the police, say sure call the Police. That should scare them off. If not then they are breaking the law if they don't leave and that's called trespassing or stalking.
A true locksmith is always able to give you at least an estimated price over the phone. Please be aware of who you call. Lockout services are always a flat rate and most car key replacements are flat rates. Most of all, read reviews before you call a locksmith. If they don't have good reviews and have some fake good reviews, then you are likely to be scammed and pay too much.
Have fun this summer and be safe. Do not leave things out in the open and if your in the back yard, then lock all the front doors, even close the garage. It only takes a second for something to grow legs and walk off.
