Subaru outback keyless entry does not work. Replaced batteries in key but the remote on key still does not unlock doors. Is there something else I can look at before I take it to an auto electrician?

sounds like you need the remote either a new battery or it needs re syncing with your vehicle , follow this link for advice
Subaru Keyless Entry Security Alarm Immobilizer Key Remote Start...

does your unlock button work in car? If it does, do you have another keyless entry key fob? If so does it work? If you just replaced the battery you can try removing battery and cleaning contacts within remote. I know some of the nissan altimas had the same issue and the only solution was a new key fob. Good Luck

If you are talking about the Key FOB, most Autozone, Advance, and Oreilys have a remote tester and batteries for the FOB.

Please rate my info.

hi
Chance are the driver side control module is not working.
Open the driver side, inner door panel and check

This could be a few things. If the security system was enabled and you just unlocked the door with a key and not using the remote, then all you have to do is put the key in the ignition and turn on/off three times. That's it!

Some cars have immobilizer keys. The immobilizer prevents unauthorized keys from starting the car (yours may or may not have it, depending on the exact Outback model).


Look here for the different styles of immobilizer keys:

The keyless entry system is controlled by the (GEM) - generic electronic module .
Keyless Entry The electronic door lock system has two main components:

• generic electronic module (GEM)(14B204)
• keyless entry remote transmitter (15K601)
• NOTE: Battery power and ground must be remove before disconnecting the GEM connectors to avoid setting false codes.
  Power Locks Operation The power locks feature allows the customer to lock and unlock the doors via momentary switches located on the driver and passenger door. When the GEM detects a momentary press of the driver or passenger lock button, the GEM will supply power to the driver or passenger lock actuators for approximately 250 ms from relays internal to the GEM. When the GEM detects a momentary press of the driver or passenger unlock button, the GEM will supply power to the driver or passenger unlock actuators for approximately 250 ms from relays internal to the GEM.
  Remote Keyless Entry Door Locks Operation The remote entry feature allows the customer to unlock the driver door, unlock all doors, and lock all doors using a valid remote transmitter as long as the ignition switch is not in RUN or START. The driver door is unlocked whenever the GEM detects a valid remote transmitter unlock transmission. All the doors are unlocked when the GEM detects a second valid remote transmitter unlock transmission within three seconds of the first transmission. All the doors are locked when the GEM detects a valid remote transmitter lock transmission. If the GEM detects a second valid remote transmitter lock transmission within three seconds of the first transmission, the doors will lock again, the horn will sound for 20 ms and the parking lamps will flash for 200 ms to indicate the doors are locked. If the GEM detects the driver or passenger door is ajar during the second lock transmission, the doors are locked again and the horn is sounded twice. If the GEM detects a valid remote transmitter lock transmission within three seconds of detecting a valid remote transmitter unlock transmission, the GEM will lock all the doors
• • The doors do not lock/unlock using the remote transmitter
  • Ignition switch.
  • GEM.
  • Remote transmitter.
  • Remote transmitter batteries.
  • GO to Pinpoint Test C .
  You followed the program instructions to the letter ? Programming -Keyless Entry Remote Transmitter NOTE: All keyless entry remote transmitters (15K601) must be programmed at the same time.
  NOTE: All previous transmitter identification codes (TIC's) will be erased when programming mode is entered.
  NOTE: To program (or reprogram) the keyless entry remote transmitters into the generic electronic module (GEM)(14B204), perform the following steps.
  
  1. Turn the ignition from OFF to RUN eight times within 10 seconds, ending in RUN. If the GEM has successfully entered program mode, it will lock and unlock all the doors.
  1. NOTE: The first TIC must be entered within 7.5 seconds of entering the program mode and additional TICs must be entered within 7.5 seconds of the first TIC. The programming mode is exited whenever the timing constraints are not met.
     Press any button on a keyless entry remote transmitter, and the doors will lock and then unlock to confirm that each keyless entry remote transmitter has been programmed.
  1. If the door locks do not respond for any keyless entry remote transmitter, wait for several seconds and press the button again.
  1. Turn the ignition switch to the OFF position, or wait up to five minutes after step 1, to exit program mode. If a keyless entry remote transmitter has been programmed (or reprogrammed), the GEM will lock and unlock all the doors one last time.
  1. Take an have the vehicle checked for DTC'S

Here's a link to program your fobs,need to do both at the same time. 2008 Subaru Forester Key Fob Remote Programming Instructions

subaru have 2 security codes one for the key/ignition switch(magnetic code)and one for the remote(rolling electronic) the car is reccognising the key but not the remotes signal to the central locking.
try locking the car with the key then pressing and the holding the unlock button on the remote for 30 secs, see if the car unlocks.if not unlock the car etc....or... put key in door and hold over for 30 secs..etc

usually after opening the door you can deactivate the alarm by pushing th unlock button or simply insert keyy in ignition and turn it on.

Get a lock cylinder from a dealer and have it re-keyed to your key!
