If you have a new Ford Mondeo 2010-2017, read on. We’re you looking for a long lasting, high-quality car key? Sorry, you won’t find it here. We wanted to share what you should expect.
Unfortunately, the new Ford Mondeo car key joins the rest of the the bad boys. They’ve trouble designed into them and this article explains why we think there’s trouble ahead.

New Ford Mondeo

There are the two main problems.

The spring mechanism isn’t up to it. We’re seeing 2-3 year-old key blades that don’t spring out anymore (which is really annoying). We’re also seeing blades that won’t stay put when folded away.

Unfortunately, when you take into account that many cars are on a three-year lease, it means that annoying and frustrating problem will be hitting the second-hand car showroom sometime soon.

Ford have stopped using the bullet proof, carbon sealed, transponder chip below in the remote keys.

The older type of chip can be driven over, dropped, and submerged in water, and it normally keeps working. They have left this foolproof design and moved over to the French-style system that integrates the chip into a circuit board.

Unfortunately, this design is susceptible to damage. Should a butterfly, on the other side of the world, flap its wings, you better watch out. Other causes for damage include being dropped, thrown, and getting wet. Just using it as a car key for more than a few years won’t help either!

This change, from a strong hardy chip, to a delicate circuit board is very disappointing. Ford car keys have always been excellent quality, but now they are the very last manufacturer to mess up. We used to give their keys a lifetime warranty, but we can’t with this key.

What can be done about this problem?

After all this gloom, there’s some good news. Firstly, the keys are reasonably priced. Expect to pay around £150 for a flip key, cut and coded from an independent. The dealers are charging around £200 we understand.

Secondly, there’s now a good fix for the broken flip problem.
A repair case is available and once everything has been swapped over, the repair we’ve seen is good quality.

The only issue is swapping the blade from your original key into the new one. The blade tang (the bit that gets gripped by the key) can be a different shape and might not slot into the new case, or be held securely. If this happens, you’ll need to get the blade cut.

The other good news about this model, is that they still use a non-rechargeable CR2032 battery.

This is good because it can be easily changed.

On the Transit and custom models, these have gone over to rechargeable batteries, which is a backwards step in our opinion.

Overall, a disappointment. Ford have always produced high quality car keys, however this is a departure from an excellent track record. Ford keys were the last to hold our lifetime warranty, but on this model, it’s no longer available.

We hope this helps you!
