2010 Nissan Lafesta Keyless Entry Failure and Flickering Lights Issue

Hi there! I understand your concern and I've indeed encountered a similar issue with my 2007 Nissan X-Trail. My keyless entry was acting up and, surprisingly, the culprit was the faulty cable connection to the outer door handle electronics, just like you suspected. This wasn't a huge deal, though the electronic flaws did cause me some inconvenience temporarily. The primary run was all about diagnosing the root of the problem, which turned out to be a faulty wiring harness. The issue scuppers the connection between the keyless system and the vehicle, hence the bizarre flickering of lights and the seemingly unusual unlocking or locking of the doors. My mechanic had to rework the connections, so it entailed a bit of labor getting the door panel off etc., but overall it wasn't an overly complicated fix. The traction of this however, is quite rare, so many mechanics might not diagnose it accurately from the get-go. So, if you decide to discuss this with a mechanic, make sure to tell them about possible cable connection problems to save your time and effort. Hope this eases your worries a bit! You've got this!

Cheers for the tip, I was completely in the dark about this! It's quite relieving to know that the issue could be something as minor as a faulty wiring harness and not an entirely bungled keyless system. Just in case I bite the bullet and get it sorted with a mechanic, do you recall roughly how much you had to hand over for the fix? And since you've done the repair, has there been any other problems creeping up that are related to this? I just want to keep an eye out for any further surprises.

Hey! You're welcome, glad I could help shed some light. I can tell ya, once you get your head around the problem, it's not as big of a nightmare as it first seems! As for the price, I remember it was around 170 Euro for the fix, most of that was actually labor cost for getting that door panel off and mending the cable connection to the outer door handle electronics. It wasn't the cheapest job, but it was absolutely worth it! Since getting it all sorted, my Nissan X-Trail runs like a charm and the keyless entry has been on its best behavior - no more unusual lockouts or flickering lights. So far, touch wood, I haven't noticed any other related problems creeping up. Just remember, it's really all about finding a mechanic you trust - someone who won't take you for a ride. Give 'em the heads up about the possible cable connection issue. It's your car, you're in the driver's seat (pun intended!). Good luck!

Spot on! I've become more resolute now and I'm thinking of getting it looked over sooner rather than later - considering your smooth sailing experience afterwards. I reckon 170 Euro isn't that steep if it ensures the end of my car behaving like a wonky disco light show. Big thanks once again for your input, and your pun gave me a much-needed chuckle! I'll keep my fingers crossed that I find a sensible mechanic who won't take a swing at my pocket. Here's to hoping for a problem-free repair ride!
