Lockout emergencies are not at all a good experience. If you just feel it’s an emergency because you would like to put your pants back on, then a 24hr locksmith is your best bet. When you find a locksmith service to contact, ensure you notify them of the emergency situation. They can then assess what is going on and determine how fast they can arrive. When you contact, ask what information they will require to let you in. If you are standing in your wrap and they need a valid ID, you may require making a few other calls. Most locksmith experts will need proof of house before they will let you in.
Luckily, most locksmith services do now offer emergency help and 24-hour service. You will pay more to have a locksmith out if he has to come at three in the morning, but you probably won’t mind. Some services even proffer a time guarantee; for a few more dollars they can guarantee to arrive within a particular amount of time.
