Car won’t start is it a Renault car key problem ?
It’s hard to imagine someone choosing all the worst car key features, and include then all in one key, but here it is. The Renault car key problem. Strap yourself in, we’ve a lot to say about these.
It’s incredible that so many people come into our shop and say the same thing..’well it’s my fault really, I did buy a Renault’. This is a shame, because people love the cars, but the keys are so, so bad, in our opinion.
Imagine the design office of Mr Renault. Picture the scene.
The Boss. ‘We’ve got a perfectly good key system. But it’s not very, how do I say?
Young up and coming designer. ‘Sexy? Cool?
The Boss. ‘Talk to me?’
Young up and coming designer. ‘I can see it now, a credit card that starts the car, thin, sleek, sexy..
The Boss. And you can make it work?
Young and up and coming designer. (Who knows very little about mass manufacture). Of course, sir, what could go wrong?
Ladies and gentlemen, we present the Laguna and Megane key cards
A House of Cards
The trouble with putting delicate electronics into a thin credit card sized key card is…well just about everything. The electronic circuits need protection against bending, twisting and any other forces that may affect them. However, Renault put them in a thin card that’s sat on, squashed, bent, and snapped.
We’ve replaced hundreds of cards in our 15 years, yet they’ve kept a similar design for the new key cards. The latest shape Scenic and Laguna have the same issues. We’re now seeing four button cards that cause the ‘card not detected’ message. It was all fine until, ‘he sat on it, my idiot husband…’
A bit harsh we think, but owners of Renault cards get so frustrated, and we tend to hear about it first.
My car won’t start, is it the key?
Rant over, let’s get to the point of this article. Renault use two sorts of car key, one is a card and the other is a traditional key. Both are causing owners to have a Renault car key problem.
Renault Key cards
To find out if the card is faulty, is very cut and dry. After putting the card in the slot, and pressing the button, it will either start, or display the message ‘Card not detected’.
If the steering lock comes off, when you put the key in the slot, then the key is recognised. However, if you hear the steering lock come off, but when you press the button nothing happens, it’s not the key.
Megane and Laguna models suffer from a host of Body Computer problems and if there’s a wiring issue anywhere, the car won’t start.
Key reader or Key card problem?
A lot of our customers believe that the reason for the car the ‘card not detected’ is the card reader. In fourteen years we’ve programmed five hundred cards plus, and in that time, we’ve seen two faulty card readers. The other times, it was a faulty key card causing a Renault car key problem.
So, before you spend money on a card reader, get the card checked. It’s easy to do. Look up your local car key man, explain the problem and ask them to check the card. They’ll put the card into a key reader that does the same thing as the car.
The key reader will be able to see if the chip can be detected. If it can’t be detected in the shop, there’s a problem with the key card.
Real keys, with blades.
The cars that use an old-fashioned key are the Renault Clio, Modus, and Wind. These all use a similar style of key, although the earlier Clio, from 2001 – 2006 has only one button. The later versions have a two or three button key.
The technology that’s inside the key, is the same as that inside the key card. Therefore, it’s still liable to damage and failure. However, because the key is stronger, the electronics are better protected. Therefore, generally, the keys last much longer than the key cards.
‘Key not detected’ is a flashing dot
On all cars with an old-fashioned key, they have used an old-fashioned immobiliser warning light. On Renault cars, it’s always a single red dot. There are three things that the red dot will do, and this will tell you if you have a problem with the key.
- Normal operation. Put the key in the ignition and turn it on (don’t try to start the car). The immobiliser light comes on for a second and then goes out for good. The car has recognised the key and will start.
- Key not detected. Put the key in the ignition and turn it on (don’t try to start the car). The immobiliser light immediately goes crazy and flashes about four times every second. This means the key is not recognised by the car. This could be either because the key is faulty, or because it’s not been programmed. The car will never forget the keys, so get the key checked out first at your local car key man. If the key’s faulty, then there’s no point paying money to try and programme the key, you are just burning good money. You probably need a new key.
- Immobiliser fault. You put the key in the ignition and turn it on (again, don’t try and start the car). This time the red light stays on solid. If the red light stays on, the car will never start. This red light is a warning to you that something is wrong. The key will get the blame, but this isn’t usually the case. Again, get the key checked out. Sometimes a new key does cure this solid light, however it normally means there is another problem on the way.
If you have a Renault car key problem, then it normally follows a similar pattern. When the problem starts, the car plays up just once in the week. You think it’s a bit odd, but put it down to nothing and then carry on as normal. Next week it does it again, a couple of times. You think there’s something happening now. The car spins over but won’t fire up. Week three it gets worse and so on. Once you get to the end, you have your fingers crossed every time you try and start the car. It will fail, and then, you’ll have a serious Renault car key problem. So, get it checked out sooner, rather than later.
The Renault car won’t crank.
This happens sometimes when the key has finally given up. The car will click, or try and crank, but nothing happens. When this happens, the red immobiliser light will stay on solid. A faulty key will cause this, but there are other problems with wiring and electronics on the car that will also cause it. Ask your local car key man to check the key, before spending any money on expensive diagnostics.
