Why is my remote not working?
If the above solutions don't help resolve your remote start issues, it might be time to head to your nearest dealer and have a look. Some key fobs can only be programmed with a special programming tool that is only available at dealerships.
But why wouldn't a remote start work? Below are some of the more common reasons why you might want to leave it to the professionals when your car's remote start has stopped working.
1. Remote starter is in valet mode
Valet mode is a safety feature that many car manufacturers use to disable remote control functions. What you'll notice is that the lock and unlock buttons work on the remote, but the home button doesn't.
This could be because someone accidentally pressed a key combination that put the vehicle in valet mode. Alternatively, it can also happen when the car is shut down for maintenance. Knowing how to remotely start the car and put it in valet mode can be beneficial.
One way to tell if your vehicle is in this mode is to look at the parking lights when you lock or unlock your car. If they don't flash, you're definitely in valet mode. Another possibility is if the remote start lights are flashing but not starting. The problem is temporary and can be reversed. You can call your dealer and have them walk you through the repair process or have the vehicle brought to you.
2. Remote start switch is off
Some car manufacturers offer a switch that allows you to disable the remote start feature. If you want to find out how to turn off a car's remote start, look for the switch. It is usually located under the dashboard or in the fuse box. It's good to note that the switch was designed to be hard to find.
Many car owners may accidentally turn it over without knowing it, which disables the remote start function. The lock and unlock buttons work, but the home button doesn't. In most cases, the problem can be resolved by simply turning the knob to re-enable the remote start feature.
3. Faulty hood opening sensor or switch
A hood pin switch is a switch that is normally installed under the hood. Disables the remote start function when the hood is open to prevent accidental engine starting. This allows you or your mechanic to work on engine parts while the engine is off.
Prevents injuries and accidents that would occur when starting the engine. Some automakers use a sensor instead of a switch. If you have a faulty switch or sensor, your remote starter will no longer work. Replacement is a simple job that any qualified mechanic can do for you.
4. Remote starter loses programming
Many remote starters are equipped with non-volatile memory that allows you to store remote control codes and programming functions. Although rare, some tend to lose their memory. After that, none of the buttons on the key fob work. Want to know how to remotely start my car?

5. Second car mode
Another rare situation where your remote start stops working is when it has the ability to start two cars. If the remote is put in second car mode, it will no longer work on the first car. If one of the two buttons is pressed, the vehicle in question does not receive any response. Consult your owner's manual to learn how to undo this or contact your dealer to resolve the issue.
