1. Check the key
The main step is to verify you’re using the correct key! In the event that you have to lift the handle before locking, try pushing it down then lifting once more.
Grease up the lock by spraying a little graphite into the cylinder.
3. Call a locksmith
On the off chance that these systems don’t work its is best to call a locksmith. A solid key could imply that your lock need replacing.
