Step-by-step on-board programming
Unfortunately, the 2019 Ram ProMaster does not support DIY on-board key fob programming. This means you cannot program a new key fob yourself using a series of ignition cycles or button presses. The vehicle's security system requires specialized diagnostic equipment to link a new remote to the vehicle's computer.
To program a new key fob, you will need to visit a dealership or, more conveniently and often more affordably, a qualified automotive locksmith.
Battery replacement
Replacing the battery in your 2019 Ram ProMaster key fob is a straightforward process.
- Locate the release button: On the side of the key fob, you'll find a small button. Press and hold it.
- Slide out the emergency key: While holding the button, pull out the emergency key blade from the top of the fob.
- Open the casing: With the emergency key removed, you'll see a small slot. Use a flathead screwdriver or a coin to gently pry open the two halves of the key fob casing.
- Remove the old battery: Carefully note the orientation of the old battery (CR2032). Gently pry it out.
- Insert the new battery: Place the new CR2032 battery into the fob, ensuring the positive (+) side faces up.
- Reassemble the fob: Snap the two halves of the key fob back together until you hear a click. Reinsert the emergency key blade.
Where to buy a replacement fob
When purchasing a new key fob, you have a few options, each with pros and cons:
-
Ram Dealership:
- Pros: Guaranteed genuine OEM part, often includes programming in the purchase price. Expertise specific to Ram vehicles.
- Cons: Typically the most expensive option. Can sometimes require an appointment and lead to longer wait times.
- Ballpark Price: Expect to pay $250 - $400 or more for the fob and programming.
-
Automotive Locksmith:
- Pros: Often more affordable than a dealership. Many locksmiths offer mobile services, coming to your location. They can typically cut and program the new key on-site. Quicker turnaround than a dealership.
- Cons: Ensure the locksmith is reputable and experienced with modern vehicle security systems. Quality of aftermarket fobs can vary.
- Ballpark Price: Expect to pay $150 - $300 for an aftermarket fob, cutting, and programming.
-
Online Retailers (e.g., Amazon, eBay):
- Pros: Potentially the lowest cost for the fob itself. Wide variety of OEM and aftermarket options.
- Cons: You
