Remote Start Not Working After Battery Change (How To Reset) - Car, Truck And Vehicle How To Guides - Vehicle Freak (2023)

The remote start is a really neat feature on modern cars. However, just like all issues related to a coded key fob, they can be a nightmare if they act up. One of the more common problems is the remote start not working after a battery change. And if that’s the issue you are facing, here is what you can do.

Unfortunately, the remote start reset procedure isn’t universal for all vehicles. It consists of a different sequence of locking, starting, and unlocking your car. Further down, you can check how to reset your remote start on an F-150, F-250, Silverado, and Ram. You will also learn where to find the reset procedure for your vehicle.

Before we go into the different reset procedures, it doesn’t hurt to ensure that a reset is what you need and learn how the remote start works.

How Does a Remote Start Work

Remote Start Not Working After Battery Change (How To Reset) - Car, Truck And Vehicle How To Guides - Vehicle Freak (1)

The remote start is essentially a separate system from the remote locking. It uses a standalone signal receiver that is encrypted to prevent theft. The signal receiver then taps into your vehicle’s tachometer, ignition switch, battery power and ground, starter motor, and brakes.

Other safety systems include locking the doors before starting the car and preventing you from engaging “Drive” before inserting the key into the ignition. Besides that, the remote start system also employs a hood switch, which doesn’t allow the vehicle to remote start if the hood is open.

So, the system by itself isn’t that complicated. It’s only a matter of tapping into the proper wires and adding a simple signal receiver. However, all the safety and anti-theft features make it extremely sensitive to any outside tampering, including a battery change.

There is also a constant debate about whether or not it can damage the engine. The argument is that letting your engine doesn’t get sufficient lubrication while idling to warm up or cool down the vehicle. That’s true to a certain extent, but anything up to a few minutes won’t hurt. And while that might not be enough to, for example, warm up the cabin, it’s enough for the car to start blowing hot air through the vents.

Diagnosing the Remote Start System

Before we go into the reset sequence, we must address other causes of a nonfunctioning remote start. The first thing to check is whether or not all of your doors are closed. If they don’t latch properly, the remote start can’t lock them and consequently won’t start the vehicle.

The second thing you should check is if the hood is closed. As mentioned earlier, the remote start feature has a non-tampering safety system switch. It doesn’t allow the vehicle to remote start if the hood has not latched correctly.

It also doesn’t hurt to check if you installed the key battery correctly. Most key fobs use a coin battery, and installing them the wrong way up is easy. That’s easy to check if your key has a signal light.

Lastly, remote start won’t work if the transmission is in “drive” or “neutral,” so make sure “park” is engaged.

If all these are good and only one key isn’t working, look at the following reset/programming procedures. However, if none of the keys work, it can indicate other more complicated issues. Either the keys are in valet mode, for which you need your vehicle’s manual to turn off, or some safety systems are faulty, like the hood switch.

Now, if everything checks out, the only thing left is to reset your car key.

Resetting your key and the remote start system is somewhat intricate, especially considering each vehicle has a unique sequence.

FAQs

Remote Start Not Working After Battery Change (How To Reset) - Car, Truck And Vehicle How To Guides - Vehicle Freak (4)

Why Do You Need Two Keys for a Remote Start?

You only need to work keys to program or reset the remote start function. Once the key is functioning, you no longer need two keys to remote start your vehicle.

Do You Still Need a Key With Remote Start?

You don’t need a key in the ignition to remote start your vehicle. You need the remote or a key fob with remote start functions. After the car is on you, there is no need to insert it into the ignition switch to drive or stop the car. However, in some cars, you might need to push the start button to be able to drive.

How Many Times in a Row Can You Use Remote Start?

Most vehicles allow you to start it remotely only two times in a row. After that, you need to start the car with the ignition switch to enable the remote start function again. Car manufacturers mainly do that for security reasons.

How Long Does the Car Run With Remote Start?

How long a car will stay on after a remote start depends on the model. The time it runs varies between 5-15 minutes. Remote start shuts the car down for security reasons and the vehicle’s longevity since idling for a prolonged time can be bad for the engine. There are ways you can extend the running time, but that’s not something we would recommend.

Can Someone Else Remote Start Your Car?

Nobody can start your car using a different remote other than yours. Also, the signal used for remote starting is encrypted, so people scanning for key fob signals will also have a hard time stealing your car. That said, automotive technology and car theft technology evolve together, so it’s always good to be careful.

Does Remote Start Unlock Doors?

If the car’s doors are unlocked before starting, the remote start system will lock them. That’s to prevent anyone from jumping in the car and driving off while you’re not looking. Once you’re near the vehicle, you can either unlock it using the remote lock buttons on the key or via the keyless entry.

Does the AC Turn on With Remote Start?

The AC would turn on with the vehicle if you left it on after turning it off. The same goes for heating. Whatever settings you selected before turning the vehicle off will remain. You can only change the AC settings remotely with newer and more expensive cars with a key display.

Conclusion

Remote start can be very helpful in extreme weather conditions. That’s why it’s such a pain if they quit working. Unfortunately, there is no simple answer to reset the remote start function after changing the battery.

More often than not, the hood switch could be acting up in which there is nothing you can do besides fixing it. We also mentioned several other causes you must address before switching to a remote start reset.

However, if you went over all the checks before resetting the key fob and all of them are ok, the best thing you can do is get a manual for your vehicle.

Alternatively, you can check the website we left earlier in the article to find your vehicle’s reset sequence. That’s if you don’t own any of the trucks we included. It’s also important to note that for many newer cars, it’s not possible to reset the key without special equipment. But, to confirm that, you can check your owner’s manual.
