How To Program A Dodge Key Fob Without A Working One?

Normally, the easiest and most straightforward method of reprogramming your car’s key fob without a working one is to go to your local dealer. However, there is a way you can do this DIY, albeit it’s a little tricky to do. So, if you lost your original Dodge car key fob, there are simple ways you can learn how to program it yourself. This applies to other cars, too.

FACT: each car has a unique tag programmed into the car’s receiver and key fob. When you purchase a new key fob, it doesn’t have this tag since the key fob hasn’t been programmed. In other words, it’s a blank key. This is why you often need the original key fob with you: this is to copy the tag from the original key into the transponder of the new key.

Without the tag, the transponder in that new key won’t be able to communicate with the immobilizer in the car. As a result, the immobilizer will disable the ignition system and the car won’t start. The programming process for a key fob usually involves using a scan tool to connect to the car. As a safety measure, it often requires the original key fob.

Thankfully, rather than needing to head to a dealership, there are ways in which you can do this yourself. Here’s a quick guide on how to program a Dodge key fob without a working one or the original with you:

Step 1: Identify What Type Of Car Key You Have

There are several ways to program a Dodge key fob without the original one. This process will depend on what type of key you have in your Dodge. Some Dodge vehicles use a separate key fob for the door lock mechanism. And, turning the key in the ignition itself doesn’t have any buttons. And it may or may not have a transponder to communicate with.

Others have the key fob, the metal key itself, and the transponder in one housing. It’s crucial that you first understand which is which before you learn how to program a Dodge key fob without a working one. Now, depending on what kind of key you have, for reference, here are just some of the tools and stuff you need to get this job done (not all, but maybe some):

• Replacement key fob; make sure you get one that’s suitable for your exact car’s make, model, and model year.
• OBD2 diagnostics scanner; connecting this to your allows you to control and program the new key fob directly.
• 4-digit PIN code; this is linked to your car’s VIN (vehicle identification number), which you can get this from a dealership or a car locksmith.
• DRB-3 scan tool; this factory scan tool is useful when the ignition key and fob are separate (dealers and locksmiths have this tool).

Step 2: Process For Reprogramming The Key Fob Without The Original

If you have the latter type of key (fob, metal key, and transponder), then here’s how to program it according to Dodge dealerships:

1. Make sure the replacement key fob is compatible with your car.
2. Enter your car and sit in the driver’s seat, close all doors, and turn the key into the “ON” position (but don’t start the car).
3. Within 10 seconds, press and release the “LOCK BUTTON” of the key fob five times in quick succession. Timing is crucial, so make sure to not miss that 10-second window and press it quickly. On some keys, you might also have to press and release the “PANIC BUTTON” five times in quick succession within 10 seconds, while keeping the “LOCK BUTTON” pressed.
4. Afterward, press and hold the “UNLOCK BUTTON” (some keys also need you to also press and hold the “PANIC BUTTON” at the same time). While holding it, insert the key into the car ignition and turn it in the ignition to “ON” mode. Do not take your finger off of the “UNLOCK BUTTON.” During this process, you might notice the door locks locking and unlocking automatically, signaling that it’s in programming mode.
5. While pressing down the “UNLOCK BUTTON”, do the same on the “PANIC BUTTON” for one full second. Afterward, release both buttons together. Some keys have a time window for this (i.e. within 30 seconds of unlocking your doors – check the new key’s instruction manual for precise steps). 
6. Next, hold down the “UNLOCK” and “LOCK” buttons together before releasing them simultaneously. Your car may chime, indicating that it’s been unlocked.
7. And finally, press the “UNLOCK BUTTON” once again. If needed, repeat this procedure to ensure that your car’s door locks are in sync with the keys.

Step 3: Troubleshooting Tips If The Programming Process Didn’t Work

If you encounter problems while trying to program the new key fob, don’t fret. It might not go smoothly the first time; this is pretty normal. Repeat the process, consult your owner’s manual for troubleshooting tips, or reach out to your dealership for help. The new, replacement key’s instruction manual might also have precise steps to follow. Here are some tips to help:

• Connection issues with your OBD-II scanner can often be resolved by checking cable connections, restarting the scanner and computer, or confirming compatibility with your car’s make and model.
• Pin code entry problems can often be solved by ensuring the code is correct and entered correctly.
• If the programming process isn’t working, verify that the key fob is compatible with your car’s make and model. Then, restart the programming process from the beginning.
• If the car isn’t responding to the newly programmed key fob, confirm it’s the correct one and start the programming process over.

When in doubt, a locksmith or your local Dodge dealership can assist further. Programming a Dodge key fob might seem complex initially, but it’s decently simple. Otherwise, a mobile locksmith is your best bet for reprogramming your key fob, and not for a lot of money. Here are a few other things to consider, as well:

• If you have a key fob rather than a conventional key, the key fob has a physical key within the fob. Ejecting them is as simple as pressing a button or sliding a switch. And, the physical key will come right out. Then, use this physical key to unlock the door by inserting it into the lock cylinder, just like you would with a normal key.
• Some Dodge cars may require you to remove a plastic piece covering the lock cylinder. Meanwhile, others have the lock cylinder immediately accessible. Most car keys aren’t unique. So, if you bought an OEM key fob specifically for your Dodge car, the lock pattern should match and you can unlock the door. But, modern car keys have transponders with a unique tag for each car. If the transponder doesn’t have a matching tag, then the car won’t run.

Step 4: Programming A New Key Fob Using A DRB-3 Tool

Note, that this alternative, optional method is for Dodge cars where the ignition key and the fob are separate. However, this method requires using a DRB-3 scan tool, which is a factory-supplied scan tool. This is the scan tool that Dodge and other Chrysler-brand car mechanics used to diagnose or program a Chrysler car from 1994 to 2007.

It costs thousands of dollars to get one. So, unless you already have a DRB-3 tool lying around for some reason, this method isn’t really viable. Not unless you want to spend thousands of dollars on a scan tool that you will rarely use. Still, if you have a Dodge mechanic buddy, you may be able to get a hold of it. In any case, here’s how to program a key fob using this tool:

1. Connect the DRB-3 tool to the car’s OBD port, which usually lies underneath the driver’s side of the dashboard.
2. Turn the DRB-3 tool, go through the menu, and select ‘DRB-3 Standalone’.
3. Select ‘Customer Preference’, there are two options, select the one appropriate to your Dodge’s model year.
4. Select ‘Program RKE’ on the menu.
5. Press enter and then hold the key fob against the DRB-3 tool.
6. Press the Lock and Unlock buttons on the key simultaneously for a few seconds, and then press the unlock button.
7. There should be a chime, and this indicates that the key is successfully programmed.

Using the DRB-3 tool, which only works for Dodge cars from 1994 to 2007 (Dodge cars after 2007 use a different type of scanner), there’s also a manual programming procedure. Here’s how to program a Dodge key fob without a working one using this tool, instead:

1. Connect pin 1 of the 16-way data link connector to the chassis ground or to pin 4 of the 16-way data link connector.
2. Close all doors and turn the ignition key off.
3. Turn the ignition key to Accessory or “ACC”.
4. Turn the ignition key off again, and the door locks will cycle once.
5. Press any button on the key fob 3 times in a row to program it. The door locks will cycle once again once programming is complete.

Step 5: Programming A New Key Fob With A Working Key

Optionally, if you have a working key, you can use a special tool called SimpleKey to program the new, replacement key. So, if you still have the original, working Dodge key fob, here’s how to program a Dodge key fob:

1. Get a hold of the SimpleKey programmer.
2. Activate the new key fob by pressing the ‘Lock’ and ‘Panic’ buttons until a blue light comes on.
3. Afterward, enter the activation code. It’s going to be different depending on your car’s make and model. But, you will find this in SimpleKey’s user manual. It will chime once it’s activated.
4. Take the SimpleKey programmer, and turn the dial according to the manual depending on your car.
5. Turn the hazard light on, and then use the working key to turn on the car.
6. Connect the programmer to the OBD port. Next, it will beep three times to indicate that it’s now communicating with the car.
7. Turn the engine off, and then pull the working key out.
8. Afterward, take the new blank key and insert it into the ignition. Press the button on top of the programmer, you should hear three quick beeps.
9. Pull the new key out, and press the button on the top again and it should chime.
10. Unplug the programmer, turn the hazard light off, and turn on the vehicle with the new key. The new key should work.

Again, this will only work if you still have the original key as it requires you to turn on the car. It will also only work with Dodge and other Chrysler-brand vehicles. If so, this ought to save you a lot on dealership fees for programming a new key. For Dodge-brand cars, this could cost you anywhere between $80 to $450 at the dealer, for the key and programming.
