Jeep Renegade Won’t Start Brake Locked: Top 4 Reasons
As said above, we can attribute this problem to several causes, some of the most common faulty parts.
That means that fixing the issue may take you a while, or even replacing a component of your vehicle, but most of the time, the issue is not as complicated to solve.
A dead battery or a faulty alternator are listed as some of the most common causes, but the issue may also originate from the starter.
Several other parts may cause your Jeep Renegade to refuse to work as intended, such as a clogged fuel filter or issues with the spark plugs or its wires.
Sometimes, this problem may also be due to a clogged air filter.
1. Faulty Battery or Alternator
The battery is one of the most important components of any vehicle, and although they are meant to last for a long time, they will eventually stop working.
When this happens, you won’t be able to continue using your vehicle.
Sometimes, the battery may not be completely faulty, but it may have some damage. It can be due to low voltage or perhaps corrosion – the causes are varied and depend on several factors, such as usage or the average lifespan of the batteries.
That’s why the first step we recommend is to inspect the battery and look for signs of damage.
If you think something is happening with it, we recommend you take it to a professional if you can’t fix the problem independently. If the issue is corrosion, you can easily clean the battery to improve its condition.
On the other hand, the problem may also be the alternator since it provides the battery with electricity.
Alternators will typically stop working due to old age or constant usage. If that’s the issue, then the vehicle won’t work at all. If this is the problem, then the solution is to replace it.
2. Complications with the Starter
If the battery and the alternator are in good shape, then you may want to check the starter and see if there’s something wrong with it.
The most obvious sign that something is not right is if you hear noises when you turn the key to turn on the vehicle. You may hear a few clicks whenever you attempt to start your Jeep.
If you believe this is the source of the issue, then you’ll have to replace the starter.
As with any other component on a car, starters tend to get old and faulty with constant usage, which means that you will have to replace the one in your Jeep at some point.
3. Brake Issues
Sometimes, the problem may be simpler than you think. It’s not an uncommon occurrence for Jeep Renegade users to not apply enough pressure on the brake pad whenever trying to start your vehicle.
This makes it impossible for the brake switch to start, and therefore, your Jeep will not work.
Another possibility you may want to consider is that you may be dealing with a bad brake light switch.
At the same time, it may seem like a harmless issue, but a faulty brake light switch may send incorrect data to the gear selector, which will then cause problems with the dashboard lights. Thus, your vehicle may not start altogether.
While the above issue is a minor one, you may also want to inspect the brake vacuum and see if there’s any issue. Brake vacuums may lose pressure sometimes, preventing your Jeep from starting.
4. Cold Weather
If you live in a cold area or are currently experiencing colder temperatures than usual, then you may want to consider it as the source of the issue.
The Jeep Renegade battery possesses something called “cold cranking amperage,” or CCA, thanks to its acronym. This aspect will allow the battery to run at 0ºF while maintaining 7.2V. The whole process only takes about 30 seconds.
However, bear in mind that this feature may be worn out if you’ve been using it frequently, causing the battery to be unable to provide CCA. It becomes challenging during the winter.
How to Fix Jeep Renegade Won’t Start Brake Locked?
The first thing we can recommend when it comes to a vehicle issue is to consult with a professional.
However, you can also attempt to solve the issue on your own if you think that it isn’t something too serious.
Here are some recommendations you may want to take into account while fixing your Jeep Renegade whenever this brake-locked issue appears:
1. Check Your Battery for Corrosion
As mentioned above, one of the most common issues when it comes to renegades that refuse to start is due to a faulty battery.
Corrosion is a fairly common problem, which means it is also easy to solve.
All you have to do is unplug the battery and clean it until there’s no sign of corrosion. Then, once you finish, you can reconnect it and continue using your car without problems.
2. Replace Your Battery or Alternator
Sometimes, the issue may not be as easy to solve as it may seem, and it may be necessary to replace the battery.
Dead batteries are another common occurrence, especially for users who have had their vehicles for several years.
Furthermore, a dead battery is more prone to creating corrosion, which means that your Renegade will be more vulnerable to damage.
Hence, we recommend you change it ASAP.
3. Change the Wiring
Sometimes, the battery is not the problem – it may be the wiring. It’s recommended to inspect the spark plugs and the rest of the wiring system to ensure that everything is okay.
If you notice that some of them are worn, perhaps it is time to replace them, as it may prevent you from starting your vehicle.
This should be done quickly to prevent further damage from occurring.
What Else Should You Take into Account?
Above, we have listed some of the most common solutions for the ‘Jeep Renegade brake locked won’t start’ issue.
However, if that has not solved your problem, maybe it’s time to consider other possibilities.
Here, we list some other useful information that you may want to take into account when fixing your Renegade.
Average Battery Lifespan
As mentioned, it’s important to keep in mind that, sooner or later, your Jeep will need a battery replacement.
That is because these batteries are useful for a period of three and up to five years.
Furthermore, it’s also necessary to conduct tests and inspect its state to ensure that it is working as intended. Your battery may start giving problems once it becomes worn out.
You may also want to take certain aspects into account to determine how long your battery will be useful.
For example, the size and type of the battery, the weather conditions, and your habits while driving. These elements will define your battery’s lifespan, for the worst or the better.
Is Your Key Fob Dead?
Sometimes, the problem may not be directly related to the vehicle. It may be on the key instead.
If you’re a Jeep Renegade user, you should know that it starts using a key fob, which makes it less complicated to start the vehicle.
However, as with any other electronic device, the key fob may stop working all of a sudden, and you may not be able to start your car easily.
That doesn’t mean that there isn’t a solution to the problem, though. All you have to do is follow the steps written below:
- First, you have to press the start and stop buttons simultaneously.
- Then, you must hit the brake.
- Lastly, apply pressure to the ignition.
Once you follow these steps, you should be able to start your vehicle without problems.
If there is no way to repair your key fob and make it work again, then you can buy a replacement.

Jump-Starting Your Jeep’s Dead Battery
If none of the solutions given above has worked, then maybe you can try jump-starting your vehicle before taking your Renegade to a professional.
You can do this by using another vehicle or a booster battery, as well as jumper cables. Alternatively, you can use portable jump starters for your Jeep.
Here’s what you need to do for this process:
- Firstly, you have to start the Electric Parking Brake. Turn on the “Park Mode”.
- You should now disable all the electric the electrical components on your vehicle. You should do the same with the other vehicle if you’re using one.
- Now, it is time to connect the cables. You should connect the positive and negative jumpers on each battery.
- Now, connect the negative to the post in your vehicle and the other end to the solid engine ground.
- You can now start the engine in the helping car. Wait a few moments, and then you can start your vehicle.
While this process may seem a bit time-consuming, it can be useful if you’re in a desperate situation.
If your vehicle still refuses to start, we highly recommend you call a professional and seek further assistance, as the issue may be more complicated and may require more intricate steps to be fixed.
