I have a 1990 740 sedan, but the seat belt system may be similar to a few other models as well.

The tongue of the driver's seat belt latch (male) is inserted into the receiving receptacle (female) by the driver's right hip. It won't come out. Pushing the red button and jiggling and prying with small tools and adding lubricant has made no difference. Presently, I need to climb in and out under the seat belt straps.

I am aware that these receptacles wear out - I replaced this very one several years ago. Yes, I will replace it again, but first I need to separate it from the seat beat latch. It feels and appears to be functioning normally, but obviously isn't. The retractors adjacent to the door work fine, which is why there is enough slack to climb in and out while the latch is stuck.

When the latch is inserted, a steel bar moves across the slotted opening, through the hole in the latch's tongue. This secures the seat belt tongue in the receptacle. Pushing the red button is supposed to release this steel bar. That steel bar through the hole in the latch won't move.

How can I release the latch from the receptacle?
Thank you!
