How To Program Ram Promaster Key

Your Ram Promaster was manufactured with advanced anti-theft technology. Inside the key fob is a transponder chip that sends electronic signals to the vehicle's ignition system.

If the ignition system senses that the wrong key has been inserted, your van will not start. The chip is programmed specifically for your vehicle, so only your vehicle responds to the signal when you click the Lock or Unlock button in a crowded parking lot.   

So, what happens if your key fob stops communicating with your Promaster? First, check the key fob's battery to be sure it's not dead.

If the battery is fine, the fob may need to be reprogrammed. You can take your vehicle to a dealership or locksmith and pay for the reprogramming or do it yourself for free.

Here are the steps you should take to reprogram your Ram Promaster's key fob: 

Step-By-Step Reprogramming Instructions

1. From Inside The Van, Lock The Doors Using Your Key Fob

Enter the van and sit in the driver's seat. Press and release the Lock button on your key fob. (If your key fob is malfunctioning, the doors may or may not lock in response.) 

2. Holding Down The Unlock Button, Insert The Key In The Ignition And Turn It To The ACC Position

Press and hold the Unlock button on the key fob. Insert the Promaster's key in the ignition. Still holding the Unlock button down, turn the key clockwise to the ACC position. Then release the Unlock button. This sequence alerts the chip in the ignition system that you are about to reprogram the chip in the key fob.

3. Simultaneously Press And Hold The Unlock And Panic Buttons; Then Release Them Together

Make sure to press the Unlock and Panic buttons simultaneously. Hold them down for 3 - 4 seconds. Release them simultaneously.

4. Simultaneously Press And Hold The Unlock And Lock Buttons; Then Release Them Together

Again, make sure to press both buttons simultaneously. Hold them down for 3 - 4 seconds. Release them simultaneously. This concludes the reprogramming sequence; you may now turn the ignition switch to the Off position and remove the key.

5. Press And Release The Unlock Button

If the van's doors were locked, they should unlock when you press and release the Unlock button. You may now exit the van.

6. From Outside The Van, Test The Key Fob By Successively Pressing And Releasing The Lock And Unlock Buttons

From outside the van, press and release the Lock button on the key fob. You should hear the door locks click shut. Next, press and release the Unlock button.

You should hear the door locks click again. If both the Lock and Unlock buttons work correctly, the programming is done! 

In the unlikely event that this sequence of steps doesn't successfully reprogram your key, go through the steps again. If your fob still doesn't work, take your van and your key fob to a Ram Promaster dealer.

The turn signal lights will flash twice, and the van's horn will emit one beep to indicate that the doors are locked. This procedure locks all of the van's doors: front, side, and rear.

How To Replace Ram Promaster Key Fob Battery?

  4. Insert the tip of the screwdriver under the bottom of the key compartment, just above the screw; pry the bottom panel up slightly. 
  5. Lift the bottom panel all the way up. The battery will become visible.
  6. Remove the old battery and replace it with a new one.
  7. Push the bottom panel back down.
  8. Re-lock the screw in the key compartment by turning it one-half turn counterclockwise.
  9. Fold the mechanical key back to its closed position.

Does A Key Fob Have To Be Reprogrammed After Replacing The Battery?

Generally, you will not need to reprogram your key fob after you replace its battery. The electronic chip inside the key fob is not dependent on the battery for its programming.

However, occasionally the chip experiences a glitch after the fob's battery is changed. So, if your key fob still isn't working and you're sure you've replaced the dead battery with a live one, try reprogramming the fob. 

If you own a Ram Promaster or other Dodge vehicle, use the sequence of steps we described in the main section of this article. If your vehicle is a different make, check your owner's manual or search the Internet for free instructions on reprogramming your key fob. 

Does Ram Promaster Have Remote Start?

Although Ram Promaster's official website does not list remote start as an available option, many Promaster owners report that they could order it through their dealers when they purchased their vans.

If you did not have remote start installed as an option when you purchased your vehicle, you could buy a Promaster-compatible remote start system, like the one pictured below, online.
