How to use remote start

Remote start, if equipped, is run from the key fob. Push and release the Remote Start button twice within five seconds. The doors lock, the parking lights flash, the horn chirps twice (if programmed), the engine starts, and the vehicle stays in Remote Start mode for a 15-minute cycle. Pushing the button a third time shuts the engine off.

While it runs, the parking lights stay on. For security, the power windows and power sunroof (if equipped) are disabled. The engine runs for only 15 minutes per remote start, and you can remote start only twice; the ignition must be placed in the ON/RUN position before you can repeat the sequence a third time.

Why remote start won't start the engine

All of these conditions must be met before the engine will remote start:

From the 2026 Ram 1500 Owner's Manual (pp. 21-22), read November 9, 2026.

If an engine fault is present or the fuel level is low, the manual says the vehicle will start and then shut down in 10 seconds. If remote start fails or ends early, the instrument cluster shows a message such as Remote Start Canceled - Door Open, Hood Open, Tailgate Open, Fuel Low, Time Expired or System Fault, or Remote Start Disabled - Start Vehicle to Reset.

How remote start heats or cools the cabin

When remote start is active and it is 40°F or colder outside, the Ram 1500 automatically turns on front defrost for 15 minutes or less, depending on the outside temperature (if equipped). In cold weather, front and rear defrost turn on automatically; the heated steering wheel and driver heated seat turn on if programmed in the Comfort menu in Uconnect Settings. In warm weather, the driver vented seat turns on if programmed.

With automatic temperature control, the climate system picks the temperature and mode based on the outside temperature. With manual temperature control, the defaults are: maximum heat with fresh air at 40°F or below; your last settings between 40°F and 78°F; and MAX A/C, Bi-Level mode with Recirculation at 78°F or above. If the truck has a rear climate system, it stays off so the front row gets the best performance.

How to drive away after a remote start

Unlock the doors with the key fob or Passive Entry, and disarm the Vehicle Security system (if equipped). Then, before the 15-minute cycle ends, press the brake pedal and push and release the START/STOP ignition button. Once the ignition is in ON/RUN, the climate controls go back to your previous settings.

On trucks with Keyless Enter 'n Go Passive Entry, the instrument cluster shows Remote Start Active - Push Start Button until you push the START/STOP button.

Remote start safety

Never start or run an engine in a closed garage or confined area. The manual warns that exhaust contains carbon monoxide, which is odorless and colorless and can cause serious injury or death when inhaled.

Keep key fobs away from children. The manual also cautions that its Sentry Key Immobilizer is not compatible with some aftermarket remote start systems, which may cause starting problems and loss of security protection.
