Nissan Proximity Key damage from changing key battery

Imagine it’s Christmas Day. You’ve done it all right. There are batteries for every present, you just need to put the batteries in! What could go wrong? Next, you open up the battery compartment and in doing so break it, so it can’t be used.  You’d be upset, your child would be mad at you and the shops would be shut. Basically you’d be screwed. Welcome to the world of the Nissan Proximity key damage. If you have one and are thinking about changing the key battery, read on.

Nissan Proximity Key damage

This week in our shop we had our first Nissan casualty due to Inferior component design. The customer had a warning on the dashboard that the key battery was low, so decided to change it (how hard can it be?). It turns out, harder than he expected and as he opened up the Nissan Proximity key, he wrecked it.

Nissan Proximity Key damage caused by bad battery change

If you watch the video below, you’ll see how the damage happened and how you can prevent it. We believe that the Nissan Proximity key damage has been caused by poor design (Inferior component design). Over thirty years ago, I worked at IBM Computers in Havant UK, making Flexi Circuits for computers. The delicate chips were protected against damage, being covered in a liquid resin material. When it dried, it protected the delicate components from damage and was important to the life of the product.

This photo shows the encapsulation process, with the resin poured over and then cured in an oven. In our opinion, this is what they needed to do with the Nissan proximity key.

To open the key, a screwdriver is inserted into a small gap and the case can be opened up. However, if too much force is applied and the screwdriver slips, it can scrape along the electronic circuit board. This photo shows the comparison between before and after.

Had it been encapsulated, as the circuits were at IBM were,  the key would have survived. Instead, this expensive, poorly designed key was wrecked. Our customer was able, clever and should have been very capable of changing the key battery, so take care when you change yours. We hope this video helps.


Nissan Qashqai Testimonial

Here is a testimonial from from another happy customer. He’d noticed the Nissan key problem getting worse and found us on-line. After driving a few hours on a saturday morning we quickly fixed the ignition, curing the problem.

So because he was so pleased, we asked him to put it on film..


Nissan Qashqai – Removing the Ignition

If you’ve read our blog previously, you’ll know that we’ve spotted a problem with Nissan Qashqai, Note and Micra ignition locks.

Over a two years ago, we looked at our first Qashqai problem.  We had the car in our workshop for a spare key, and couldn’t remove the customer’s key from the ignition!

That’s Odd!

We had to take off the ignition and strip it down while the customer waited in our reception area. This gave us an insight into the problems you must have. So we dug a bit deeper into the problem, and found a solution.

In this world of DIY, we know that some of you out there want to try and get it fixed, without taking it to Nissan. We’ve a made this video that will show you clearly what you need to do.

Here is a testimonial from one of our customers who watched the video and saved themselves time and money..

Getting ready to remove the ignition

To take the ignition off the Qashai, Note or Micra, you just need some basic tools. A philips screwdriver, a hammer and a really sharp punch is all you need.


These seem a bit basic, but we use them day in and day out in our workshop in Lincoln. We fix between twenty and forty locks every month and post them all around the UK after they’ve been refurbished.

Is Nissan Qashqai DIY for you?

If you still fancy getting the lock off yourself and stripping it down, you’ll we’ll send you a two videos over the next few days.

Before you start, you’ll need to arrange for your car to be off the road for the day, so don’t leave it blocking in cars, or parked where it shouldn’t be!
