So, you’ve got yourself a Dorman Key Fob Programmer and you’re ready to get those fobs working. The big question is: does this Dorman device actually do the job? The short answer is yes, it should. These programmers are designed to get your key fobs synced up with your vehicle’s system, allowing you to regain remote entry and other key fob functions. However, there are a few key things to keep in mind to ensure a smooth programming process, and one of the most crucial is your car’s battery.
One common concern when using any type of automotive programmer, including a Dorman key fob programmer, is battery drain. Leaving your car’s ignition in the “ON” position for programming can put a strain on your battery. To avoid any unexpected issues, especially getting stranded with a dead battery mid-programming, it’s highly recommended to connect your vehicle to a battery charger or maintainer. This provides a stable power source throughout the process, preventing your battery from draining to the point where it can’t start the car.
If you find that even a relatively short programming session seems to significantly drain your battery – enough to prevent your car from starting – it’s a red flag that your battery’s health might be compromised. In such cases, it’s wise to investigate your car battery and charging system further. A simple way to start is by using a voltmeter to check the battery’s voltage directly at the battery posts and then at the terminals.
To accurately assess your battery, perform these voltage checks both when the car is off and while someone is cranking the engine. When the car is off, the voltage readings at the posts and terminals should be virtually identical. Similarly, during cranking, the voltage at both points should also be consistent, although naturally lower than when the car is off. A noticeable difference in voltage between the posts and terminals, particularly during cranking, suggests a connection problem. This could indicate corrosion or loose connections between the terminals and the battery posts themselves, hindering proper power flow.

A healthy car battery in good condition should be able to maintain the vehicle in the “ON” position for a reasonable duration, around 30 minutes, especially if unnecessary electrical loads like the heater blower, radio, and exterior lights are turned off. If your battery fails to do so, it could point to a few potential problems. First, the battery itself might be nearing the end of its lifespan and unable to hold a charge effectively. Alternatively, the battery installed might not have sufficient cranking amps (CCA) for your vehicle’s requirements. Consult your car’s owner’s manual for the recommended battery specifications to ensure you have the right type installed.

In conclusion, Dorman key fob programmers are generally effective tools for programming your key fobs. However, being mindful of potential battery drain during the process is crucial. By using a battery maintainer during programming and regularly checking your car battery’s health, you can ensure a smooth key fob programming experience and avoid unexpected battery-related issues. If you encounter persistent battery problems, it’s always best to consult a qualified mechanic to diagnose and address any underlying electrical system issues.
