Why Radio Stays on When Car is Off and Door is Open? How to Tackle the Problem?

Operating a car radio without a working motor may not be a major issue. However, if such a thing happens for an extended period of time, the batter is likely to be drained. As a result, you may be unable to run your car. Thus, turning off radio when not in use is necessary.

In most cases, the car radio will not turn off due to improper switch wiring or a broken wire. A poor ignition button or a faulty cylinder switch are two extra possible causes.

So why radio stays on when car is off and door is open? There are some issues related to the working radio even after you turn off your car. But don’t worry. Possible solutions are available. Let’s scroll down to discover.

When Should the Radio Turn Off

The radio may turn off in various ways, according to your car type, radio setup, and how you connect the components.

  • First, turn the radio off manually. You’ll have to push the start button manually or utilize the remote for it to stop working.
  • Second, when the ignition is in its “start” mode, the car radio will switch off.
  • Third, for some cars, when you switch it off, the radio will stop immediately. For some other car models, the radio will stop 10 minutes after you switch off the car or when you open the car door.

Why Your Car Radio Wont Turn Off When Door Opens Even with the Ignition Off

1. The construction of an electrical circuit

When the ignition is working, the car connects to bypass the electronic circuit. The turned key shuts the electrical circuit, allowing the radio to remain, even if the key is in “off” mode.

2. Red wire and yellow wire concepts

Your car radio’s yellow wire is consistent, absorbing electricity and serving as a memory line. The wire ensures that your radio always has the right time, date, and radio settings, even if you have turned off your car and left it for a long time.

The red wire serves as a trigger for turning on the radio when the keys are all in the ignition.

Some drivers would like to keep the red and yellow wires active at all times. Even while the keys are not in the ignition, the radio may remain and play continuously. In this case, just turn the radio off manually.

Other Reasons Why Radio Wont Turn Off When I Open Door

1. Incorrect wire set ups

Another problem with the wires is the incorrect setup. It’s possible that you hooked the wires to the wrong connecting locations, enabling your car radio to stay turned on. Thus, you should check the yellow and red wires to see if they are in the correct connection points.

2. Broken ignition switch

Your radio may not turn off due to a broken ignition button. Your car radio should switch off if the ignition is on. Also, the radio should only be active if the ignition is off.

Besides, even if the ignition button isn’t running, there would be enough electricity to power the car’s gadgets.

3. Key and cylinder

The ignition cylinder may be wearing out. In this case, you may mistakenly believe it is in this “off” mode although it is actually in this “on” position.

4. Preset radio component

Some cars include a method that enables them to do pre-programmed duties for a set period. This function involves leaving the car radio on with a set duration of time.

5. Shut-off delay

This problem is uncommon compared to other cases. Some car radios can be defective. The radio may remain on even if it is set to turn off after the door is open.

You may check the manual to determine if the car’s radio offers this feature. Please remember that radios older than 15 years may not include this feature.

If your radio lacks this feature, the issue might result from a broken door switch.

How to Fix When the Car Radio Won’t Turn Off When the Door Opens

Try out the steps below to clear every potential reason why the radio does not switch off when you open the car door.

Step 1: Check the wiring

It’s possible that the wiring isn’t working properly. A car radio generally includes two power lines and a wire.

One of the power cords is always hot. The other wire is only functional when the car is operating.

As soon as hot power connects to the core wire, the radio may keep working. You can check by using a voltage or a check light. Get a power source that only warms up while the ignition is in this accessory setting when both wires are always hot. After that, you may use it to activate the radio according to your purpose.

Step 2: Check the ignition button

Even after you take the key out, the car radio stays on with ignition off. If the wires get hot without a power source, such as the one described in the preceding step, the ignition button may be the cause of the problem.

Determine if the accessory’s power supply is accessible while this key is on the “inactive” mode. If the accessory has the power, you should modify the cylinder. Install the new ignition button if necessary.

Step 3: Check the key and cylinder

Examine the key and ignition cylinder to check whether they are too old or not. If this is the case, you need to remove the key when the switch is still in the “on” mode.

To fix the problem and switch off the radio, ensure that the ignition button is not in the “on” state when you take out the key. It would be best to change the broken cylinder to address this issue entirely.
