2021 RAM 1500 Owners Manual - KEYS

KEYS

Your vehicle is equipped with a key fob which supports Passive Entry, Remote Keyless Entry (RKE), Keyless Enter-N-Go (if equipped), and Remote Start (if equipped). The key fob allows you to lock or unlock all doors, tailgate, and the RamBox (if equipped) as well as activate the Panic Alarm from distances up to approximately 66 ft (20 m). The key fob does not need to be pointed at the vehicle to activate the system. The key fob also contains an emergency key, which is stored in the rear of the key fob.

The key fob’s wireless signal may be blocked if the key fob is located next to a mobile phone, laptop, or other electronic device. This may result in poor performance.

If your vehicle is equipped with a Wireless Charging Pad, the key fob may not be found if it is placed within 15 cm (150 mm) of the pad page 77.

With the ignition in the ON position and the vehicle moving at 2 mph (4 km/h), all RKE commands are disabled.

In case the ignition switch does not change with the push of a button, the key fob may have a low or fully depleted battery. A low key fob battery can be verified by referring to the instrument cluster, which will display directions to follow.

A low key fob battery condition may be indicated by a message in the instrument cluster display, or by the LED light on the key fob. If the LED key fob light no longer illuminates from key fob button pushes, then the key fob battery requires replacement.

To Lock/Unlock The Doors And Tailgate Push and release the unlock button on the key fob once to unlock the driver’s door, or, twice

within five seconds to unlock all doors, the

tailgate and the RamBox (if equipped). To lock all the doors and the tailgate, push the lock button once.

When the doors are unlocked, the turn signals will flash and the illuminated entry system will be activated. When the doors are locked, the turn signals will flash and the horn will chirp.

All doors can be programmed to unlock on the first push of the unlock button. The horn chirp when the lock button is pushed can be programmed on/off within Uconnect Settings page 237.

Air Suspension (Remote Lowering Of The Vehicle) — If Equipped

For easy entry and loading, your vehicle can be lowered by pushing the key fob air suspension lowering button two times. When air suspension

lowering is requested using the key fob, the vehicle will send a series of chirps and flashes to alert the customer that the operation has begun and will continue these alerts until it successfully lowers.

The following conditions must be met for the vehicle to lower remotely:

The vehicle must not already be in Entry/Exit (Park) ride height.

The vehicle battery must be fully charged.

All doors must be closed.

The key fob must be out of the vehicle. NOTE:

Ensure the vehicle is clear of all objects, pets, and people prior to remote lowering.

Vehicle lowering can be cancelled at anytime. When vehicle lowering is cancelled, the vehicle will raise up to the next defined level and lock out the remote lowering feature until the ignition has been cycled ON/OFF.

To cancel vehicle lowering, push the key fob air suspension lowering button one time during the lowering process. When vehicle lowering is cancelled, the horn will chirp two times and the turn signal lamps will flash four times. Once raising is completed, the horn will chirp one time.

More information on air suspension is provided later in this manual page 165.

When replacing the battery, ensure the (+) sign on the battery is facing upward. Avoid touching the new battery with your fingers. Skin oils may cause battery deterioration. If you touch a battery, clean it with rubbing alcohol.

Replace the battery by using your thumb to push down and slide the battery under the small lip on the top edge of the opening.

To assemble the key fob case, line up the top edge of the back cover with the top of the fob, and press the edges into the interlocking hinges until all edges snap together with no large visual gaps.

Reinsert the emergency key until it locks into place.

The key fob battery should only be replaced by qualified technicians. If the battery requires replacement, see an authorized dealer.

Programming the key fob may be performed by an authorized dealer.

Once a key fob is programmed to a vehicle, it cannot be re-purposed and reprogrammed to another vehicle.

Only key fobs that are programmed to the vehicle electronics can be used to start and operate the vehicle. Once a key fob is programmed to a vehicle, it cannot be programmed to any other vehicle.

Duplication of key fobs may be performed at an authorized dealer. This procedure consists of programming a blank key fob to the vehicle

electronics. A blank key fob is one that has never been programmed.

When having the Sentry Key Immobilizer system serviced, bring all vehicle keys with you to an authorized dealer page 482.
