It’s great to hear your new key fob is up and running! Now, let’s tackle the crucial question: does that Dorman Key Fob actually get the job done when it comes to programming? Many users wonder about the reliability of aftermarket key fobs like Dorman for vehicle programming, and it’s a valid point to consider.
Generally speaking, Dorman key fobs are designed to be compatible and functional for programming to your vehicle, offering a cost-effective alternative to original equipment manufacturer (OEM) fobs. They are intended to meet the necessary specifications to communicate with your car’s computer system and successfully program new keyless entry functions.
However, it’s wise to proceed with a little caution, particularly concerning your car’s battery during the programming process. Whenever you’re engaging in electronic procedures like key fob programming, there’s always a potential draw on your vehicle’s battery. To avoid any unexpected issues, it’s a smart practice to connect your car to a battery charger or maintainer while you’re programming the Dorman key fob. This precautionary step ensures that your battery voltage remains stable throughout the process, preventing any chance of draining the battery to the point where your car won’t start.
If you find that even a relatively short programming session, say around 10 minutes, seems to significantly deplete your battery to the point of preventing ignition, it’s definitely worth investigating your battery’s health. A multimeter is an invaluable tool for this. Start by checking the voltage directly at the battery posts (where the cables connect to the battery itself) and then compare that reading to the voltage at the battery terminals (the clamps that attach to the posts). Do this with the car off and also while someone attempts to crank the engine.
Ideally, the voltage readings should be consistent between the posts and terminals in both scenarios (car off and cranking). While cranking, the voltage will naturally drop, but a significant voltage difference between the posts and terminals during cranking points to a potential connection problem at the terminals. This could indicate corrosion or a loose connection that needs immediate attention.
Furthermore, a healthy car battery in good condition should be able to sustain the vehicle in the “ON” position (with accessories powered but engine off) for approximately 30 minutes, provided you minimize power draw by turning off unnecessary accessories like the heat blower, radio, and exterior lights. If your battery fails this simple test, it might suggest that the battery is either under-sized for your vehicle’s requirements in terms of cranking amps or is simply nearing the end of its lifespan and needs replacement.
In conclusion, Dorman key fobs are generally effective for programming, offering a viable solution for replacing or adding key fobs. Just remember to take the precaution of using a battery maintainer during programming and consider any unusual battery drain as a signal to assess your car battery’s overall health and connections. This proactive approach will ensure a smooth key fob programming experience and help you avoid potential battery-related headaches.
