Key head halves won't snap together

[Long Islander]

I had to replace the key fob battery on both my design key head and my original black spare key. The two clamshell key head pieces on the design key snapped back together just fine. But the original black key head won't snap together with the electronics inside. If I remove the electronics, the two halves snap together and stay shut -- with or without the rubber gasket. But when I put the electronic chip inside, I can't get the two halves to snap together -- even without the rubber gasket. The battery is in correctly, and the chip fits inside just fine.

I've spent over an hour on this, and I have two sets of black key heads, but I just can't get the key head shut.

Any ideas?

Try turning it over.

LI - I had the same issue. Try putting some oil on a q-tip and running it around both the rubber seal and the other half where it connects.

This should allow it to snap in

I finally got it to snap back together. The circuit board was positioned correctly. The notches ensure that it is either in or not. Also, you can't put it in upside down.

So, how did I do it?

I think all the pieces just had to sit out in the open at room temperature and humidity for a couple of days after sitting in the safe for the last 12 years (that's when I bought the fireproof safe and where I keep my extra keys). It's a fireproof safe and I keep a lot of silica gel packets in there, so there is very little moisture. Perhaps that caused the plastic pieces to shrink a little. All's well now.

Another bit of trivia about the remote key. If you're not in range of the car, the red light won't blink. Go figure.
