Experiencing intermittent starting problems with your 2011 Nissan Murano can be frustrating, especially when you’ve already addressed common culprits. If you’re facing a situation where your Nissan Murano sometimes refuses to start, even after replacing the key fob battery and the starter motor, it’s time to explore other potential causes, especially those related to your 2011 Nissan Murano Key Fob Replacement and its interaction with your vehicle’s starting system.
It’s not uncommon for owners of the 2011 Nissan Murano to suspect the key fob when faced with starting issues. While you’ve already replaced the key fob battery, and even tested the old one to find it was still at 3V, the problem persists. This indicates the issue might not be a simple case of a dead key fob battery, but could be related to the key fob itself or the car’s receiver for the key fob signal.
Here are a few areas to investigate concerning your 2011 Nissan Murano key fob replacement and starting problems:
-
Key Fob Signal Interference or Weak Signal: Even with a new battery, your key fob might be experiencing signal interference. Try starting your Murano in different locations, away from potential sources of radio frequency interference. A weak signal from an aging key fob can also cause intermittent starting issues. While you may not need a complete 2011 Nissan Murano key fob replacement immediately, signal issues can sometimes be resolved by reprogramming the existing fob or ensuring the car’s receiver antenna isn’t obstructed.
-
Key Fob Programming Issues: It’s possible that the key fob’s programming is becoming corrupted or is no longer being correctly recognized by your 2011 Nissan Murano. While less frequent, issues in the car’s immobilizer system or the key fob’s transponder chip can lead to starting problems. A diagnostic scan of your vehicle’s computer system can often reveal if there are any fault codes related to key fob communication or the immobilizer.
-
Car Battery Issues (Intermittent): Although your battery tested good at O’Reilly, intermittent battery problems can be tricky to diagnose. Voltage tests might show a healthy battery, but issues like loose terminals, corrosion, or internal battery faults that appear under load can still cause starting problems. Ensure your battery terminals are clean and tightly connected.
-
Starter Motor Installation or Related Wiring: Since you recently had the starter motor replaced, it’s worth double-checking the installation. While unlikely, loose wiring connections to the starter or solenoid could cause intermittent failures. It might be beneficial to have the mechanic who performed the starter replacement re-inspect their work.
-
Automatic Trunk Gate and Electrical Issues: You mentioned issues with your automatic trunk gate not latching via the fob or dashboard. This could be an independent problem, but it’s also possible it’s related to a broader electrical issue within your 2011 Nissan Murano. Electrical gremlins can sometimes manifest in seemingly unrelated systems.
While a 2011 Nissan Murano key fob replacement might seem like a potential solution, it’s crucial to perform thorough diagnostics to pinpoint the exact cause of your starting problems. Before considering a new key fob, ensure you rule out other potential electrical or mechanical issues. A professional mechanic with experience in Nissan vehicles can perform a comprehensive inspection, including checking for fault codes, testing the key fob signal, and evaluating the car’s electrical system to accurately diagnose and resolve the starting issue you are experiencing.
