Tired of using your key as a pull doorknob? Keys are fragile… and honestly, what if it breaks off in your lock? Then what? Locksmith? But he’s busy and can’t get there for 3 hours. Plus, he’s dirty because he hasn’t showered in 2 days. Meanwhile, your dog just redecorated your bathroom because you can’t let him out. All because you didn’t have a pull tab on your lock. Price-wise, this is far cheaper than the headache you’re going to have with that brittle key.
