Battery went dead and the transmitter (fresh batteries) will not unlock the doors. Ive read that it's possible to have "Pop-A-Loc" to come and use the inflatable pillow to open back door then climb into front open hood charge battery and then release the front lock I was also wondering if there is anyway to open the hood by reaching up from under the car?? Is it really that crazy??? Any tips, suggestions, anyone have??? Again, I looked all through the Cadillac forums and was unable to find a similar problem, lots of computers locking...but no issues with not being able to get in, except someones passenger door and there were no replies to it. Im asking for a desperate friend - thanks in advance!!
