Ultimately it is up to you to watch out for you. Double check your window and door locks before you go to bed and before you leave your house. Watch out for people who are paying too much attention to your activities. Don't let a weak point of entry allow access for a burglar to penetrate your house or business. Stay vigilant.
AVOID LOSING KEYS
When you come home make sure to put your keys in the same place every time whether it's a short stop or you are coming home from work. Having a routine and sticking to it is the best way to remember where to find your keys. When you go out, use the same pant's pocket.
AVOID SCAMMER/FAKE LOCKSMITHS
Too many fake companies are out there posing as locksmiths. Make sure that whoever you call provides you with a name of the technician, they arrive in a marked vehicle and can show identification. It only takes a few seconds to check out if the company you are calling has legitimate credentials. It is your security after all.
DON'T USE KEYBOXES
Key boxes are almost always more vulnerable to penetration attacks than the locks on your door. That means someone with bad intentions who has a little training can open the lockbox easily which gives them not just access to your house or facility, but they can open all your locks.
Poor door fitment is the number 1 reason that obtaining access to your house or facility is so easy. Also, proper door fitment helps to keep your utility bills low because proper fitting doors slows/stops air from moving through the door.
