I had a copy of the valet key made however when I use it it sets off the alarm so I have to get in quick and get the fob to stop the alarm. No metal to hide a key so I duct taped it in an inconspicous place. It works so far but we haven't had freezing temps yet. Thank goodness I was worried about locking the key in and hid a key as we were hours from home and someone accidently hit the lock button as I said the alarm went off but I grabbed my fod and stopped it. I'm a new Dodge owner and miss the keyless entry I had previously.
