Yes,

Your seat belt retractors are ten years old.

I would replace them if they become a nuissance especially when they start getting caught in the door upon closing and chewing up the door panel and B-pillar coverings.

Just keep the key off when you unplug the srs connector on the retractor, you may also want to disconnect the battery, but it really is not necessary, but you will set an SRS code if the key is on when you unplug the connector from the retractor.
