Why is my Volvo s90 key not working?

When I grab the handle to unlock the vehicle, it takes about 5+ seconds to unlock and multiple grab attempts.

I’m not sure this is a fob battery issue, as if for example I drive to the store and come back out, it works immediately. It always seems to be worse after a day or so of the vehicle not being used.

Does anyone else experience this?

This past November, my driver door handle was replaced because it was not retaining the code or something to that effect.

I was not able to replicate in front of the Volvo service center, despite 3 + reports to them. I had changed my Key FOB battery and emptied my pockets of Bluetooth devices (e.g.,Tile, Apple AirPods and case). I still sporadically encountered the issue.

Fortunately, in November, the Volvo service center actually encountered the same problem for themselves. They said the handle was not «holding the codes» and they replaced it (under warranty).

Co dělá špatný snímač rychlosti vozidla?

You probably know/have tried this already but I believe mobile phones can interfere with the signal. If I have a problem I normally find that moving my mobile phone from my right pocket (closest to the car) to my left hand or left pocket fixes the issue. This may or may not be your problem but worth a try.

I’ve noticed this happening recently too. It takes a few pulls on the handle before it unlocks the door. Or need to unlock via the key fob button.

Was curious if this might be related to fob battery.

I was having similar issues so I finally changed out the battery with an IKEA battery that I had in my drawer. The problem persisted. I was ready to go to the dealer but bought a new Eveready battery, one of their better ones, and the problem went away. It walrus like new. YMMV

My unlock button on key fob doesn’t work reliably in morning now. But after a trip it becomes much better. This makes it hard to diagnose. Maybe I will try a new battery first.

I have the exactly same issue. I could not use my key to unlock the car in the morning, but my wife’s key works fine. So every morning I have to use my wife’s key to open the door first. My key will then work fine for the whole day. Really weird experience, not sure how to fix it.

Check the remote battery. According to Volvo, it needs to be between 2.7v and 3.3v. However, I have had customers with complaints about remote function with voltage around 2.8v to 2.85v that I’ve replaced the battery for with no further problems.

And the handles don’t store any codes. They are just antennas.

Fair enough. There could be a terminology or translation gap. The service advisor indicated that it was not holding or retaining the code. Maybe they meant «receiving» the code.

I definitely replaced multiple key fob batteries — verifying that the last Duracell I installed had five years before the expiration.

I have not ever had my Key FOB not work. My issue was that the proximity sensor on the driver’s door was not allowing me to open the locked door with a touch. No other electronic devices of any kind except the Key FOB in my pocket or around me.

The bottom line my issue, similar if not identical to OP, has completely gone away with the replacement of the driver door handle.

I explain this, not to be argumentative, but to be informational.
