You walk up to your Dodge Challenger, press the button, and nothing happens. The silence is loud. You check the dash, but it stays dark. It feels like a nightmare when you have somewhere to be. I will show you how to find the problem, fix it, and get back on the road.
You need to check the basics first. Start by replacing the fob battery because it is the most common culprit. If that fails, inspect your main car battery for signs of corrosion or a loose connection. Use a multimeter to verify voltage levels. If the lights work but the engine does not turn over, look for a bad brake light switch or a starter relay issue.
Why the Push Button Fails
When your car refuses to start, the frustration kicks in fast. Many drivers panic, but the fix is often simple. You just need to look at the system in pieces.
Dead Fob Battery
A weak key fob is the usual suspect for a car that will not wake up. The signal becomes too faint to reach the car sensor. You can pop the back off and swap the coin cell. It takes seconds. Once you have a fresh battery, try the start button again.
Weak Car Battery
Your Challenger needs a lot of power to crank the engine. If the main battery is old, it might light up the dashboard but fail to spin the starter motor. Check for white crust on the terminals. Clean them off, and make sure the cables are tight. It helps a lot.
Blown Starter Fuse
Power flows from the battery through a fuse to reach the starter. If that fuse pops, the car gets no message to start the engine. Check your fuse box located under the hood. Look for a burned wire inside the plastic casing. If it is broken, swap it out.
Faulty Brake Switch
The car computer must know your foot is on the brake before it lets you start. A bad switch prevents this signal. If your brake lights do not turn on when you push the pedal, this switch is likely the cause. It is an easy part to reach under the dash.
Bad Starter Relay
The relay is a small switch that handles the heavy power needed for the starter. It can wear out after years of use. If you hear a single click when you press the button, the relay is a prime suspect. Swap it with a matching one to test it.
Corroded Ground Cable
Electricity needs a path to travel back to the battery. A loose or rusty ground wire stops the flow of power, which leaves you stranded. Check the thick black wire that connects to the engine block. Scrub the metal contact point with a wire brush to restore the connection.
Take your time when you inspect these parts, and always double check your work. These steps cover most common problems people face with their ignition system.
- Check the fob battery
- Inspect main terminals
- Test the starter fuse
- Verify brake lights
- Swap the relay
- Clean ground cables
Dodge Challenger Push-start Not Working
The push-start system relies on a constant flow of power to the computer. When that flow breaks, the car ignores your command. This often happens because the car does not recognize the key. You should try moving the fob closer to the dash button.
Key Fob Recognition
The car constantly looks for a signal from your key. If the signal is blocked by your phone or other metal items, the car acts dead. Pull the key out of your pocket, and hold it directly against the start button. This bypasses interference and often works for a quick start.
Security System Lock
Sometimes the car security system gets confused and thinks someone is stealing it. This is a common immobilizer issue that prevents the engine from turning. You can try locking and unlocking the doors with the fob to reset the alarm. Then try to start the car once more.
Neutral Safety Switch
Your car will not start if the computer thinks it is in gear. This is a safety feature to stop the car from moving. Make sure the shifter is firmly in Park. You can try moving it to Neutral and back to Park, which resets the sensor connection.
Dashboard Message Alerts
The car talks to you through the screen. If you see a warning about a key not found, the receiver is the problem. This part hides behind the dashboard. It is a rare failure, but it happens after a failed start attempt leaves the computer in a weird loop.
Starter Motor Failure
The starter motor can break down after years of heavy use. If you hear grinding sounds or nothing at all, the motor might be seized. Tap the starter with a hammer to free it. This is just a temporary trick, so you need a new part soon.
Voltage Drop Issues
A car computer needs a steady flow of voltage to function. If your alternator output voltage is low, the computer shuts down to save power. You might notice dim lights or a slow crank before the car stops working. Use a meter to check the charge level now.
Always prioritize safety when you work near the starter or battery terminals, and keep your tools organized. A drained car battery can cause many codes that confuse the computer, so check the voltage before you replace any expensive parts or modules.
- Use a fresh fob battery
- Hold the fob against the button
- Shift to neutral and back
- Listen for starter clicks
- Inspect the dashboard warnings
- Tap the starter if needed

Is the Key Fob Battery Dead?
You might think the car is broken, but often the key is just tired. A weak fob is a common ignored warning light sign. The car cannot detect the signal, so it stays locked in a safe mode. You should always keep a spare battery in your glove box for trips.
The process of opening the fob is simple. You usually slide a small tab, pull out the mechanical key, and pry the plastic shell apart. Be careful not to bend the plastic clips. Once open, the round battery slips right out. Make sure you buy the right size at the store.
If you put in a new battery and it still fails, the fob might have lost its programming. This happens if the fob gets wet or dropped on hard concrete. You can try to re-sync it by following the manual, but you may need a dealer for a reset.
Never assume the worst right away. A simple fob issue is cheaper than a new starter motor. Check your fob, test the battery, and try the push button again. If the lights on the dash flicker but the engine stays silent, you have confirmed the fob is not the primary issue.
- Test the fob battery voltage
- Clean the internal fob contacts
- Remove nearby electronic interference
- Replace the coin cell battery
- Check for broken fob buttons
- Reprogram if the signal fails

Why Does the Engine Not Turn Over?
If you press the button and hear nothing, the starter is not getting power. This usually points to a bad ground or a dead main battery. It is a classic sign of an electrical system failure that stops the engine from firing up. You need to verify the power flow.
Check the battery terminals first. If they are loose, the car cannot draw enough amps to crank the motor. Tighten them with a wrench, and see if the dash lights get brighter. A solid connection makes a huge difference in how the car reacts to your inputs.
Sometimes the starter solenoid is the weak link in the chain. It takes the signal from the button and sends it to the starter. If the solenoid is stuck, you get silence. You can use a screwdriver to jump the starter terminals, but be very careful of sparks.
Remember that a bad alternator can lead to a dead battery after starting your vehicle multiple times. If your car dies while driving, the alternator is the prime suspect. Keep an eye on your voltage gauge while the car runs to spot trouble before it leaves you stranded.
- Tighten all battery cable connections
- Scrape corrosion off the terminals
- Check the main starter fuse
- Test the starter relay switch
- Inspect the neutral safety sensor
- Confirm the alternator charging rate
Can I Bypass the Brake Switch?
The brake switch tells the car the driver is ready to start. It is a safety item, but it can fail like any other plastic part. If your brake lights not working occurs at the same time, you know the switch is broken. Do not try to bypass it permanently.
You can reach under the dash to find the switch near the top of the pedal arm. It has a small plunger that moves when you press the brake. Sometimes the plunger gets stuck. You can spray some cleaner inside to free it up for a little while.
If you are stuck, you can try to press the pedal very hard. Sometimes this makes a weak switch connect for one final start. Do not rely on this method. Replace the switch as soon as you can to avoid getting stranded at a store or work.
A new switch is very cheap and takes ten minutes to put in. It fits into a bracket and locks with a simple twist. You will be back on the road without worrying about the car not starting again. It is a smart repair to handle yourself.
- Locate the switch on the pedal
- Check the brake light bulb
- Clean the switch plunger tip
- Test the pedal connector wire
- Verify the fuse for brakes

Will a Bad Relay Stop the Start?
The relay is an electromagnet. It pulls a metal contact shut to send power to the starter. If the internal coil burns out, the circuit stays open. You will press the button, and the car will do nothing at all. This is a very common starter relay issue.
You can find the relay inside the fuse box under the hood. It is usually a square black box. Look at the diagram on the lid to find the one labeled starter. You can pull it out and swap it with a horn relay to see if the car starts.
If the car starts after the swap, you found the problem. Just buy a new relay from any auto parts store. They are universal in many cases. It is a cheap fix that saves you from a high tow bill or a long wait at a mechanic shop.
Never try to force a relay into a slot if it does not fit. You could bend the pins and cause a short. If the relay looks melted or smells like burning plastic, the socket might have heat damage too. Check the wires under the relay block for any signs of melting.
- Locate the starter relay box
- Swap with the horn relay
- Test the start button again
- Buy a matching part number
- Inspect the relay socket pins
- Check for burnt plastic smells

Frequently Asked Questions
Is It Safe to Jump Start a Car with Push-start?
Yes, you can jump start it like any other car. Connect the cables to the battery terminals, and make sure the other car is running. Do not touch the cables together, and start your car normally after waiting a few minutes for the charge.
Can a Bad Battery Cause a No-start Condition?
Yes, a bad battery is the most common reason for a push-start failure. If the battery cannot provide enough cold cranking amps, the starter will not turn. You should always test the battery voltage before you start replacing more expensive parts like the starter.
Are There Hidden Keys in the Fob?
Yes, every fob has a mechanical key hidden inside. You pull a small release tab to slide it out. This key allows you to open the driver door if the car battery dies. You can use it to get inside and pop the hood to reach the main battery terminals.
Do I Need to Program a New Fob?
Sometimes you must program a new fob, but often you can sync it with your existing keys. Check your owner manual for the specific steps for your model year. If you only have one key, a locksmith or the dealer will have to help you program the new one.
Does a Push Button Wear Out?
The push button can wear out after many years of use. The internal contacts get dirty or break down from moisture. If you press it and nothing happens even with a good battery and relay, the button itself is the likely failure point for the ignition system.
Should I Disconnect the Battery Before Working?
You should always disconnect the negative terminal before you work on the starter or alternator. This prevents accidental shorts that can damage the car computer. It is a basic safety step that keeps you and your vehicle safe while you perform the repair work.
Will a Blown Fuse Prevent Starting?
Yes, a blown starter fuse stops all power to the starter circuit. Check your fuse box diagram to find the right one. If the metal wire inside the fuse is broken, the power path is gone. Replacing the fuse is a quick and cheap way to fix this issue.
Can Cold Weather Kill the Battery?
Cold weather drains battery power very fast. If your battery is already weak, the cold will finish it off. The oil also gets thicker, which makes the engine harder to turn. This combination is why many people find their cars will not start on the first frosty morning.
