The seat belts in my truck locked up once, first the driver side, then a week later the passenger side. My electronics were all pluged in and they just wouldn't unlock no matter what I tried. Since I didn't want a seat belt ticket, and I couldn't justify the cost of new electronics and/or seat belts I removed the wiring, removed the seatbelt fom the seat and removed the locking mechanism. My seat belts might not lock to save me in a crash, but I haven't been irriated since with them locking when I don't want them too.
