Hi i just had a new alternator put in my mazda 323 astina and now no power to central locking was working before the alternator was replaced???

Most likely the battery was disconnected when replacing the alternator. I would double check the wire connections on the battery to the alternator.

Audi central locking

Lock ALL DOORS, Disconnect the Battery... Wait 2-3 minutes and connect the battery and it should reset itself. Make sure all doors are LOCKED...

AND that you have a KEY to open the door in case it does not work.

My Yukon won't start.

My 02 trailblazer pulled that stuff on me. Finally disconnected both battery posts, touched together for 60 seconds. Pulled both PCM fuses together, reinstalled, reconnected the battery and started fine. Gremlins at play I guess.

Locked out of car and have tried key manually with no joy,battery totally flat

Hi Cruicks.
Unlock the trunk (boot) and follow the wiring through to the central locking unit for the trunk lid....find the connector plug and disconnect it....Using the cables going into the car (not those connecting to the solenoid) Get a charged battery, take two cables (not too heavy) and connect one to positive and then plug that into the socket you've disconnected....Take the other cable and connect it to the negative side of the battery...flash it onto the open hole on the connector....The locks will either open or re-lock....If that happens, reverse how you've connected the two cables....Hey presto....

I put coke (soda pop) on my battery posts to clean them and now when it starts I have to hold my foot on the gas. 97 Jeep Grand Cherokee limited.

It sounds like you have a brand new problem besides sticky battery posts. Make sure that you have reconnected any additional wiring to the posts. Mainly the ground wire. Usually it's a 12 guage short wire that connects to the negative battery post and connects to the inner fender well farely close to the battery. How long was the battery cables disconnected from the battery? More than 10 minutes? Most newer vehicles that have been disconnected from battery power for 10 minutes or longer after being reconnected, has to re-learn how to work or run. Fter being diconnected from power that long a time erases the memory from the computer.
