Seatbelt Buckle Problem

[Redback]

Does anyone have experience with D4 front seat belt buckle playing up? The passenger's side won't accept the lap shash tongue bit.

No noticeable damage, I can push a trim remover in with no issue, but not the buckle tongue. I've been trying to figure out how to get it apart to see if there's something stuck in there and stopping the latch from opening/moving properly.

Reading about pretensioners, breaking one is not ideal. A replacement is potentially $200 plus, $500 plus for the OEM part, so I am hoping a repair is possible.

Not heard of this one - maybe a coin or something like that got in there? Does the tongue go all the way in, or is it stopped early? (ie, is this a latching issue?)

Can you tip it over to have something fall out, or is it a bit too short for that?

The seats are fairly easy to pull out with the buckle attached, though certainly heavy...
