Why Your Nissan Remote Start Isn’t Working and How To Fix It

Has your Nissan remote start stopped working even with a fresh battery in the key fob? Getting into your vehicle on cold winter mornings can become more difficult if your remote starter fails. This handy guide covers the most common reasons a Nissan remote starts malfunctioning and troubleshooting tips to get it functioning again.

What Causes a Nissan Remote Starter to Stop Working?

There are a few typical culprits when your Nissan’s remote start feature doesn’t kick in:

Weak Key Fob Battery

The battery inside the key fob remote can drain over time. If it gets too low, the signal can’t reach your vehicle effectively. Easy check: replace the battery and try the remote starter again from the maximum allowed range.

Out of Range

Standing too far away from your Nissan when hitting the remote start button can prevent the signal from connecting. Heavy rain or other weather can also impact connectivity. Move closer and try again.

Interference

Other electronic signals in the area can potentially block the connectivity between your key fob and your vehicle’s receiver. This depends on the frequency and strength of local signals.

How to Troubleshoot a Nissan Remote Starter

First, determine whether replacing the battery provides a quick fix. If not, try the following troubleshooting sequence:

Inspect Key Fob Battery Level

Pop open your key fob and check the battery condition first. Look for corrosion or leaks. Replace the battery even if you see only a low warning light. Use a fresh CR2032 coin cell battery.

Resync Key Fob

Your Nissan dealership can re-register and resync your key fob to the vehicle if the battery fix doesn’t work. This reestablishes the connectivity. Cost is around $100.

Replace Key Fob

If resyncing fails to restore function, the key fob may require replacement by your dealership. Cost ranges from $180-$350 for the fob and programming.

Electrical and Mechanical Inspection

For a remote start system to activate the ignition, a sequence of critical wiring and components must operate:

  • The fuse box delivers power
  • The starter motor cranks the engine
  • The ignition switch allows the spark plug firing
  • The engine computer boots up

Any issues in this sequence will prevent remote start capability. Best to have your Nissan dealer or technician troubleshoot potential electrical gremlins or mechanical faults.

Regain the Convenience of Remote Start

Following some simple troubleshooting when your Nissan remote start to stops working can help restore this very convenient feature. Check the battery, resync the fob, replace it if faulty, or pursue inspections to pinpoint electrical and mechanical issues. With the right diagnostics and repairs, you’ll stay cozy getting into a prewarmed vehicle on those cold winter days.
