CT5-V 2025 CT5V BW battery dead, drivers manual key entry not functional

[DZnutz]

So, quite the problem I have here. I was going to hook up a battery tender to my brand new BW thats in storage... well, turns out the battery is already completely dead and the only other physical way to open the car... drivers side manual key, is not working. key turns fine, you can hear the mechanism actuating but it doesnt unlatch the door.

Local Dealer has no other options other than roadside to get into the car but Im certain I know how theyll want to do that and Im not risking bending the door frame or breaking and scratching trim.

So... are there any people here who have run into this and still managed to either unlock the car or atleast get into the trunk or pop the hood?

I can only imagine that there is a way, just need someone whos been as unfortunate and as persistent as me previously.

The car is on a hoist so access to the underbody is no issue if the hood latch can some how be accessed and popped from underneath.

Any thoughts are appreciated

Since you can access underneath, maybe try supplying power to the starter via jumper cable? That should get you enough power to open a door.

Sadly this is an area where the 4 is better than the 5. The 4 retains the mechanical door locks so if you lose power you can still open the door.

Very curious idea... Ill have to explore that but if someone else has any other ideas theyd be appreciated as well

Here's another option:
1. Remove the front bottom plastic cover so you can access the hood release cable.
2. Pull on the cable to access the hood (this assumes the CT5 routes the hood cable the same as the CTS in the video)
3. Charge or jump-start the car

Good ideas guys, can any one confirm if the ct5v actually has an emergency hood release accessible from the exterior of veh?
