2014 Sante Fe key fob causing alarm to go off when jostled
 

So we got this 2014 Santa Fe a couple months ago and it's been fine up until this past week. Now whenever the key fob gets even slightly jostled, it causes the alarm to go off. It's not the end of the world, but it's pretty annoying. I took the fob apart, replaced the battery, and checked to make sure the internal components were still intact. Everything looks fine, but as soon as I grab the key off of the key holder to leave the house, the alarm goes off. Then when exiting the vehicle, I have to make sure to hold the fob steady in my hand until I'm out of range so it doesn't set the alarm off. Any suggestions? I'm trying to avoid having to pay for a new key.

Thanks in advance for any help.
