Tesla’s electric vehicles (EVs) have revolutionized the automotive industry with their advanced technology and eco-friendly performance. However, an intriguing aspect of Tesla cars, their charge ports, has become a focal point for tech enthusiasts, particularly those wielding a device known as Flipper Zero.
In recent months, videos and social media posts have surfaced showing people using a Flipper Zero — a small, open-source hacking and testing device — to unlock Tesla charging ports.
But how true are these claims?
This guide explains what’s really happening, how the Flipper Zero works, and why using it to interact with vehicles like Teslas raises legal and ethical concerns.
🚗 What Is the Flipper Zero?
The Flipper Zero is a multi-tool for pentesters, researchers, and hardware enthusiasts.
It’s designed for testing and interacting with various wireless signals and access systems.
It can:
- Read and emulate RFID/NFC cards
- Capture and replay infrared signals (like remote controls)
- Send Sub-GHz radio signals (used by garage doors, car fobs, etc.)
- Act as a Bluetooth or USB debugging tool
💡 The Flipper Zero is legal to own and use — as long as it’s used for legitimate security testing or educational purposes.
🔋 Why Tesla Charge Ports Are Being Targeted
Tesla charge ports (on most models) can be remotely unlocked to allow charging.
Normally, this is done in one of three ways:
- Pressing the button on a Tesla charging cable.
- Using the Tesla app or in-car screen.
- Using a compatible third-party charger or adapter.
The button on the Tesla charging cable sends a wireless Sub-GHz signal that tells the car to open the charge port door — a convenience feature, not a security flaw.
🧰 How the Flipper Zero Fits In
Some users have discovered that the Flipper Zero can replicate the same Sub-GHz signal that Tesla’s charge cable uses to open the port.
Essentially, the Flipper can:
- Capture the open charge port signal (which is unencrypted).
- Replay it to trigger the charge port latch on nearby Teslas.
⚠️ This does not unlock the car, start the engine, or access Tesla’s systems — it only opens the small charging port door.
🧪 What’s Actually Happening
According to discussions on the Flipper Forum and open-source repositories like GitHub (UberGuidoZ), users have shared signal files (.sub) that can open Tesla charge ports.
These files mimic the same frequency and signal pattern used by Tesla’s own charging equipment.
However:
- The signal is not encrypted, meaning it can be replayed easily.
- It only opens the charge port door — it does not unlock the car or allow charging.
- Tesla is aware of this behavior and may update firmware to mitigate it.
⚖️ Is It Legal?
Using a Flipper Zero to open your own Tesla’s charge port is not illegal.
However, using it to interact with someone else’s vehicle without consent can violate local laws related to:
- Unauthorized access to property
- Tampering with vehicles
- Interference with wireless signals
🚨 Even if it seems harmless, opening another person’s Tesla charge port without permission can be considered vandalism or harassment.
🧠 What Tesla Owners Should Know
If you own a Tesla, here’s what you can do to protect your vehicle:
- Keep your car updated.
Tesla frequently releases over-the-air updates that can modify wireless behavior. - Park in secure or monitored areas.
Reduces the chance of someone tampering with your vehicle. - Use Sentry Mode.
Tesla’s built-in cameras can record anyone approaching your car. - Don’t worry too much.
The charge port opening signal doesn’t expose personal data or compromise security.
🧩 What Flipper Zero Creators Say
The developers behind Flipper Zero emphasize that the device is meant for ethical hacking, research, and education — not malicious use.
They’ve also stated that:
“Flipper Zero is a tool, not a weapon. It can be used responsibly for learning and testing, but abusing it for unauthorized access is illegal.”

🔒 Will Tesla Fix This?
Tesla could address this minor issue by:
- Encrypting the charge port signal
- Requiring authentication from the vehicle or Tesla app before opening
- Changing the Sub-GHz frequency in future models
As of 2025, Tesla has not confirmed any major firmware updates specifically targeting this behavior, but the company regularly tightens wireless security across its systems.
🧰 Summary: Flipper Zero and Tesla Charge Ports
| Question | Answer |
|---|---|
| Can Flipper Zero open Tesla charge ports? | ✅ Yes, it can replicate the unencrypted signal used by Tesla’s charging cable. |
| Does it unlock or start the car? | ❌ No, it only opens the charge port door. |
| Is it dangerous? | ⚠️ Not directly, but misuse can be illegal or considered tampering. |
| Can Tesla prevent it? | ✅ Yes, through firmware updates or signal encryption. |
| Should owners worry? | 😌 Not much — it’s a minor inconvenience, not a major security flaw. |

✅ Final Thoughts
Yes — people are using the Flipper Zero to open Tesla charge ports, but it’s not a hack in the traditional sense.
It simply replays an unencrypted signal that Tesla’s own chargers use.
While it’s mostly harmless, using it on someone else’s vehicle is illegal and unethical.
If you’re a Tesla owner, keep your software updated and use Sentry Mode for peace of mind.
Flipper Zero remains a powerful tool for learning and testing, but like any tool, it should be used responsibly.
Flipper Zero and Tesla Charge Ports
The Tool of Choice
Flipper Zero is a multi-tool for tech enthusiasts, capable of interacting with various wireless protocols. Its NFC (Near Field Communication) functionality has been the focus of recent attention due to its ability to open Tesla charge ports.
How It Works
All Tesla vehicles use a standardized NFC code to open their charge ports. Flipper Zero users can easily emulate this code, triggering the port to open without needing the car’s key or app.
A Harmless Prank or a Security Concern?
While some see this as a harmless prank, others raise concerns about potential security risks. Repeatedly opening and closing the charge port could potentially cause wear and tear. Additionally, if someone with malicious intent were to use this technique, they could disrupt charging sessions or potentially even cause damage.
Tesla’s Response
Tesla has not yet issued an official response regarding the use of Flipper Zero to unlock charge ports. However, some users have reported that Tesla Service Centers can reprogram the NFC code, making the car immune to this particular exploit.
The Debate Continues
The debate surrounding the use of Flipper Zero to unlock Tesla charge ports continues within both the Tesla and Flipper Zero communities. Some argue that it’s a harmless prank, while others see it as a potential security risk that should be addressed by Tesla.
The Flipper Zero / Tesla Charge Port Prank
The Flipper Zero, a multi-purpose hacking tool, gained notoriety for its ability to potentially unlock Tesla charge ports in 2022. While the technical capability exists, the situation is nuanced and requires a closer look.
| Aspect | Evidence | Counter-evidence |
|---|---|---|
| Technical Feasibility | – Flipper Zero can transmit radio signals mimicking those used by Tesla chargers to open ports. – Online communities share files and tutorials for this purpose. | – Tesla has implemented rolling code updates and other security measures to mitigate unauthorized access. – Not all Flipper Zero devices are compatible with the required frequencies. |
| Prevalence of Misuse | – Anecdotal reports and forum discussions suggest some individuals have attempted using Flipper Zero on Tesla charge ports. – The extent of actual misuse is difficult to quantify and may be exaggerated. | – No widespread reports of large-scale unauthorized charging or damage to Tesla vehicles. – Tesla actively monitors for security vulnerabilities and takes countermeasures. |
| Potential Risks and Consequences | – Unauthorized charging could lead to financial losses for Tesla and inconvenience for legitimate users. – Tampering with charging systems could pose safety risks. | – The likelihood of such harm is relatively low due to Tesla’s security measures and the limited scope of reported misuse. – The act of unauthorized access to a vehicle or its charging system is illegal and can have legal consequences. |
Overall, while the Flipper Zero’s technical ability to unlock Tesla charge ports exists, the prevalence of actual misuse appears limited. Tesla actively works on improving security, and the potential risks associated with unauthorized access are outweighed by the implemented safeguards.
It’s important to remember that using the Flipper Zero for unauthorized access to Tesla charge ports is illegal and can have serious consequences. This information is for educational purposes only and should not be used to promote or condone illegal activity.
