A seat belt that will not retract usually has a jammed pawl in the retractor, a twisted belt, or a deployed pretensioner after an accident. Here are the five most common causes and how to fix each.

A hard yank during a stop locks the inertia pawl. Slowly pulling the belt fully out (no jerks), then releasing, almost always resets it. Cost: $0. DIY: Easy. Severity: Low.

Only short distances at low speed to reach a shop. A belt that does not retract still buckles and locks during an impact, but the slack lets you slide forward more than safe.
If a pretensioner fired, yes, the SRS code clears once the new tensioner is installed. Some cars need a scan tool to clear the stored code.
Not recommended. Used belts can have hidden tensioner damage, frayed webbing, or stretched fibers from a prior impact. Always buy new from a dealer or trusted brand.
$200-$500 typical. Some manufacturers offer a free seat belt replacement after any accident as a goodwill program - ask before paying.
No - never spray oil, silicone, or lubricant inside a seat belt retractor. It contaminates the webbing and prevents the pawl from locking in a crash.
Plastic parts in the retractor shrink in cold weather. Old or worn retractors that are borderline jam in winter and work fine in summer. Replacement is the long-term fix.
