Need to change the battery, stuck at a store. Tools needed and location of battery would be awesome. trying to make battery change asap

sound like sticking choke or could be computer settings try dis connecting battery post for a few minutes ground side of battery would be sufficient .

Contact the store
Should have a warranty

Change batteries ASAP because if your batteries die you will be unable to get into the safe without the key. The batteries are located inside the safe. If you can't open the safe, you can't replace the batteries!!!

There are NO replacement keys available for model #45891. We've tried. I would NOT buy this safe again for these reasons.!!!

First of all I need the make and model and year of the car to tell you where the battery is.

First, The Porsche Cayenne can have two batteries. The primary is located under the driver seat and the secondary is under the rear trunk/subwoofer. The battery that usually goes bad is the primary. Most auto stores will NOT change this battery for you because of location (Autozone, Pepboys, Advance, O'rielly, Napa). Its very easy to do but you will need a triple square 10mm bit (autozone or napa carries them)
Remove front plastic trim piece by pulling forward
Using triple square bit unbolt the front two bolts
Tilt seat back (helps to move the seat forward once bolts are removed)
Remove plastic battery protector
Remove/replace new battery
Make sure to plug the vent line back into battery

Unbolt the crossbar over the washer fluid bottle there should be two screws holding the bottle. Once they are out you will be able to have easy access to the battery.

try holding the key on the left that looks like an arrow. While holding this key hit LGLG. Then change the warning portion to debugging. hit the menu key to erase the log.

On cars with 4 wheel disc brakes the rear calipers are what they call racheting.The pison needs to be turned clockwise at the same time you are pushing in.This mechanisum is for the E brake system.They make special tools for doing this that you can pick up at your local parts store.

CCA is not as important as standby amp hours in your location. The bigger the battery the better when dealing with large vehicals with a lot of electrical demand.
