I have just purchased an 04, V70 wagon …. The key FOB works but the key just swings loose in the FOB. Is there an easy fix for this?

Welcome Steve!
Funny, I just finally (after ~ 10 years of ownership) fixed the switchblade key on my 311k mile XC70. The key had been just like yours since I bought the car in 2012. It was never a big deal, I just always inserted it so that the fob wouldn’t dangle down by my leg. The fix took maybe 10 minutes. I’m allowing the glue to set up overnight, so technically I guess it’s more like a 12-hour repair.

There’s several videos online, most depicting a procedure that involves using a narrow kerf saw to cut the halves apart. I had a junkyard key on hand so I just took a stab at it with a flat blade screwdriver & it came apart nicely, no cutting involved. Pretty easy to figure out how it works & what has gone awry you’re once inside. All you’ll likely need from your donor is the actual switchblade button.

Anyhow, welcome aboard!

I bought replacement cases and transponder chips. Transferred/repaired as needed and had the units reprogrammed at the dealer. The transponder chips do fail and obviously prevent the car starting. I swapped the springs and mechanical keys over, although I think I paid $15/key to have a locksmith here cut new ones from the blanks that came with the fobs.
