Why does my seatbelt lock?
The Reason Your Seat Belt Locks Up…
Your seat belt was designed to lock up at particular times by utilizing a device called a retractor. ... Or, the belt may have twisted and caught behind the pillar trim. Unfortunately, once it's activated, the belt has to fully retract before you can extend it again.
How do you unstick a seatbelt strap?
First, pull the webbing out of the seat belt completely and then give it a yank to undo the locked belt. If this does not work for you, take the retractor out of the vehicle. Then, using a screwdriver you can manually spin the spool. This will cause the seat belt to slowly retract back into the mechanism.
