Central Locking Keyfobs

Central Locking Keyfobs

Types

Due to the change from Smartlock to Smartshield midway through the AU Falcon S1 production, the key fobs for these cars are split in 2

S1 Smartlock

These remotes are actually inherited from the EL Falcon before it, and are a 304mHz sender with a Ford specific secure code built in to discern individual remotes. As a result of their age, finding good condition original ones are becoming harder, and even once found the rubber buttons are prone to wearing quicker than their S2-3 counterparts. They appear to use a fixed code sending mechanism, however the specifics of each fobs codes is yet to be decoded

As of time of writing in 2024, the only manufacturer of “off the shelf” aftermarket keyfobs for this model is KEYDIY, however their remotes have a high failure rate. Please see the list in the Aftermarket Replacement section for better remote clone options

S2/S3 Smartshield

these remotes are far closer to what would become the standard for the BA/BF model Ford Falcons after them, however they still employ a 304mHz frequency. These remote have more aftermarket replacements available* an are easier to find replacements for due to their relatively higher commonness, and appear to employ a double-length security code with some form of “code-hopping” to discern specific remotes and prevent a common method for breaking in respectively, theoretically making them more secure. They are noticeably larger than their S1 counterparts, however they are also far more durable, reparable, and ultimately, replaceable*

Programming Keyfobs

The following steps must be started within 10 seconds of closing the door

These steps will not work if you’re cars electronic locks are faulty i.e if the lock actuator requires rebuilding

  1. ensure all doors are closed and car is unlocked, then insert the key into the ignition and turn to the “ACC” position (1 click from off, not 2)
  2. press the rear demister switch 3 times. If successful, the door locks should cycle (unlocked-locked-unlocked)
  3. press any button on the remote. once registered, the car should cycle the locks again
  4. repeat previous steps for any other remote
  5. remove key
  6. done

Changing locking mode (Smartshield models only)

In the Smartshield models of AU Falcon (Late Series 1 - Series 3), a locking mode can be specified using a factory remote. Note that this does not work on any known aftermarket remote, only the Ford OEM Remotes. To change the remote mode, simply hold down the lock and unlock buttons at the same time for approximately 3-5 seconds, the car will acknowledge with a flash of the indicators. The 2 modes available are:
