Вольво s40 ошибка ключа зажигания

My Volvo S40 (06) would not start when I turned the ignition key. I got a message that was somewhat like «Key Error, please try again». I tried with both my keys so it wasn’t the key itself. I think I could hear some relay clicking in the on position. I had the same error about a week earlier but then it worked after a few tries and I didn’t think more of it, but this time it would not work.

I called the Volvo assistance and the guy they sent put the key into the ignition, turned it fully on and hit it relatively hard about ten times with the handle of a screwdriver, then he turned it to the off position and repeated the procedure.

The car then started. He said that he had fixed this problem on a few Volvos and they seemed to continue working after this, but he could not guarantee anything.

I am not a mechanic (obviously) so I wonder if someone knows what this error could be. Is it just oxidized connectors or is it a symptom of some bigger problem? What can I do about it?

I recently had a similar problem where I got intermittent «Immobilizer» messages.

According to my mechanic (20+ years of Volvo experience) the connector between the antenna ring and the wiring harness sometimes causes problems — taking it off, spraying it with contact cleaner, and re-seating it fixes these. It could be that the vibrations from hitting the key were enough to overcome the resistance and allow the key to be recognized & the car started.

It’s a relatively simple job to get to and clean the connector, which might be good preventative maintenance.

Other possibilities: You could have a bad relay. There’s a fusebox under the hood, and one of the relays (R13) is for the starter. You should be able to remove the relay, and jumper the connection to determine whether or not the relay is the problem. You can get the wiring diagram for the car here.

Finally, you could have an intermittent connection to the starter, or a bad starter.

If you had given that description without the screwdriver part, it would sound to me like your car is one of those that has a chip in the key where not just any key matching the physical cut will work, it has to be in combination with the car reading the chip. The goal being more security to keep someone from getting a hold of your key and making a copy of it or trying to circumvent the physical portion of the ignition.

These were the precursor to the keyless ignitions that are found on more and more cars these days where you don’t even have to put the key in, just have it in your pocket.

Perhaps the transmitter/receiver is in the steering column as the key would be in the ignition when it is trying to read it and hitting the key in the ignition caused enough vibration to jossle the transmitter/receiver. Volvo may have had a manufacturing issue on that model of a weak soldering joint or similar causing an intermittent issue to develop over time.

I just experienced the same deal. However, the fix didn’t entail any sort of weird mechanical voodoo. I just changed the battery on the key fob.

The symptoms were the following: (1) was able to control door locks remotely, (2) the key hole would emit weird clicking sounds, (3) the status on the console read «Key Error». I called my trusted Volvo mechanic and his first suggestion was to just change the battery first. Worked like a charm!

For the 2005 S40, you’ll need a CR2032 with the positive end down. All the best to y’all.

Yes i had a look at a s40 2005 model today, The customer was left with no ignition and no crank but wipers interior light, main lights all worked,

After a lot of tracing i found that the ignition switch to be faulty no main ignition circuit out put, when i used my back probe the car started perfect,all circuits worked,,

This may help i would definitly go to ignition switch first,,

I had the same problem this morning with my 2007 s40 2.0D. The car has 125,000 miles on the clock and up until now has been very reliable.

I went on a short journey this morning parked the car as normal and locked it with the key fob. On my return the car unlocked with the key fob, but when I tried to start the engine the radio & dash board operated as usual however when I turned the key to position 3 the engine would not turn over.

When the key was turned there was no sign that anything was happening, no clicks from the starter motor or audible noise from the fuel pump etc.

I had to leave the car there and went home to check the web to see it this had happened to anybody else, and I stumbled on this site, I decided to try this remedy as I had nothing to lose, and to my surprise it worked.

I held the key in position 3, then hit the end of the key firmly with a screwdriver handle, and the car started.

Try it, it worked for me!!

Had the same problem with my 2.0D V50 137000 miles on the clock never had a problem with the immobiliser before.
Was waiting to pick daughter up from work engine running okay, turned engine off for a few minutes whilst waiting for her. Everything was normal lights, bells and whistles but engine would not even turn over, no matter what I tried nothing. Got out of car and functioned the door lock to see if it would start, nothing!!
Three hour wait to be recovered home, when I put the car in the drive I tried it again and got a one off message never had again «Immobiliser check manual» message.

Trawled the Internet for answers, tried the function lock and unlock the door five times nothing. Disconnected the battery overnight still nothing.
Checked the relay (R13) and starter relay wires all fine.

At this point was thinking I’m looking at replacing the antenna ring and seeing pound note signs rolling over!!

Checked the passenger fuse box connections all fine and came across this one of «tapping the key» whilst key in position three.

So put key in ignition, turned key to position three and tapped it two or three times with back of screwdriver handle and the car burst into life.

Magical screwdriver now kept in glove box should the need arise.👍👍
