2003 audi a4 door wont unlock with or without key after changing battery in key fob


Your KEY will not unlock the Door? That has nothing to do with the FOB.

OR do you mean your FOB will not work at all?. If it is a PROGRAMMING ISSUE, you need to contact your Dealer

2003 audi a4 had dead battery, charged battery and now the key fob won't work and the security lights flash for about 5 min everytime I do anything to the car. why ?


Synchronization
When
Key buttons operated repeatedly while vehicle out of range and system becomes inoperative. Key batteries replaced.
How - early models
Depress lock or unlock button. Manually lock and unlock driver's door within 30 seconds. System should operate normally after approximately 1 minute. If not, carry out programming procedure.
How - late models
If vehicle locked, manually unlock driver's door using key. Press key unlock button once. Switch ignition ON and OFF. Remove key from ignition switch. Press key lock or unlock button once. System should now operate correctly.

I have a 2001 audi a4 cant program the remote i tried the 2 key thing the lihgt will flash once like there spose too but nothing after that


1. Put a key in the ignition and turn key to On position (not running)
2. Get out of the car, but the unpaired fob in the drivers door and turn it to the lock position, then while holding it there, press the lock or unlock button on the new remote.

If this doesn't work, change the battery's in your key fob,

if that doesn't work, check your fuses , number 14, and 38

Program a remote key for 03 A6


I have an A4 and did this to re-program my key:

1. used the key to start the car...then turned it off
2. put the key in the driver door (door closed)
3. pressed the lock button on the key fob once
4. turned the key to lock the door.

This is basically the steps in the owners manual, but the car must be started with the key first, and the key must be in the door lock before pressing the lock button.

Need to program remote keyless entry for 2003 nissan pulsar?


If it is a 2003 model year vehicle follow this procedure. If it doesn't work, you may have the wrong fob which happens all the time.

Sit in vehicle and close all doors.
COMPLETELY insert and remove ignition key more than six times within 10 seconds.
Hazard lights should flash twice.
Turn ignition to ACC position
Press and hold any button on the new key fob hazard lights will flash twice
For a second key fob using the master lock switch, lock and unlock the doors then hold down any button on the second remote until the hazard lamps flash twice.
Then you are done open the door to exit the programming mode.
If the lamps didn't flash when holding down the key fob make sure you have the right key fob, they are different for each car.
