Automakers love to tout “smart” security features. But for one Ram driver, the system’s smarts feel more like stubbornness by blocking his key fob from unlocking the truck just because he left the window open a little.

The clip from truck enthusiast still-stockF150 (@still_stockf150) has captured the attention of more than 19,000 viewers. In it, the frustrated owner stands outside his pristine blue truck, mashing the buttons on his key fob and unable to unlock the vehicle.

“Got my windows cracked. My truck is locked,” he narrates. “I go try to unlock it and I get a red notification on my key fob.”

Separating Myth from Mechanism

Despite the owner’s frustration, there’s no evidence that Ram intentionally disables the key fob when a window is cracked. No official owner’s manual or technical bulletin mentions such behavior. What Ram enthusiasts and modders do discuss, however, are features that allow you to roll windows down (and sometimes up) using the key fob, but those hail from prior generations or rely on aftermarket toggles.

For instance, older Rams around 2012 and earlier included functionality to lower the front windows by pressing the unlock button twice and holding it. It’s a feature drivers likely found useful in sweltering heat. Many lament its disappearance, as it appears to have been discontinued around the 2013 model year due to liability concerns: A few owners accidentally left them cracked during storms, leading to interior damage and consumer complaints.

Since then, tech-savvy owners have turned to tools like AlfaOBD or Tazer modules to reinstate these features, adding functionality through coding rather than from the factory.

The comments section on the clip included several Stellantis owners pointing out they had no similar experiences with their own vehicles, which suggests the video creator had some kind of anomaly going on.

What Could Actually Be Happening?

There’s no clearly documented “window‑crack lockout” protocol in Ram trucks, but several technical explanations are worth exploring:

Signal Interference or Dampening: Standing close to a cracked window may change the key fob’s radio-frequency signal path, especially if there’s moisture or metallic tinting near the breach. RF-sensitive systems can be finicky under such conditions, especially in newer vehicles using ultra-low-battery signals or more stringent proximity sensing.
Key Fob Unpaired or Security Glitch: Anecdotes on Reddit detail random key‑fob unresponsiveness in 2024-25 Rams, sometimes resolved by opening and closing the driver’s door or using the Ram app to re‑authenticate it. These may be minor bugs in the vehicle’s security or convenience features.
Aftermarket Mod Contamination: If the vehicle in question has ever had a Tazer, AlfaOBD, or similar module installed, even temporarily, it could be triggering unexpected behavior. The module may inject code or logic that overrides factory protocols.

What Should Drivers Do Next?

For these seemingly unexplained but persistent problems, there are some across-the-board steps to take to try to get some answers:

Reach Out to Ram/Stellantis: Since no official documentation confirms that locking a Ram with a cracked window disables remote unlocking, your safest bet is to ask directly. Consult the 2025 Ram 1500 Owner’s Manual for existing remote keyless behavior and follow up with Ram support for confirmation or clarification.
Survey the Community: Several Ram owners report similar frustrations. One driver described how their 2025 Ram would randomly refuse to lock or unlock until they opened and closed the driver’s door. Another worked around a “key not detected” error by pressing the fob directly against the start button, triggering re-authentication. Scouring forums and comment threads can help you see if this is widespread or isolated.
Run a Diagnostic Scan: In one case, a 2019 Ram owner encountered fob failures coinciding with the installation of an interlock device. Dealer advice included checking fuse F24, wiring integrity, and potential anti-theft “lockdown,” then targeting Body Control Module (BCM) diagnostics. A professional scan may uncover electronic or software indicators that explain or fix the behavior.
