If the key fob ceases to function then you must replace it or purchase an alternative from an authorized dealer. There are many reasons why the key fob won't be working, including a dead coin battery, receiver module issues signal interference, an internal electronic chip issue.

A dead coin battery is the most frequent reason behind a key fob that isn't working. Check the battery to make sure it's in the right place and not leaks. Replace the battery with a fresh one of the same size and voltage. Examine the contact points of the battery to make sure they are not damaged and clean.


Water damage is a different reason the key fob might not work. If the key fob has been exposed to salt, soapy, or dirty water, it could cause permanent damage. You can test this by removing the battery in the key fob, and cleaning it using isopropyl or electronic cleaner.

You can try to reprogramme your key fob through an OBD-II scan in case it has been damaged. This will reset all on-board computers and will allow the key fob to function again.

If your SEAT Leon's remote keyless system isn't functioning, there are some things you could try. Make sure the battery in the key fob isn't dead. It typically lasts between two and four years before it deteriorates. Also, try locking and unlocking the vehicle with an extra key to see if it works. If the key fob does not work after trying several times it could be because the receiver module installed in the vehicle could be the source of the problem.

Another reason that can cause a key fob not locking or unlocking is water damage. If the key fob has been exposed to water that is clean from a tap or rain and it's not a huge issue, but if it's taken a bath in soapy or salty water, it could have a faulty electronic chip inside that requires reprogramming. If the key fob is still unable to unlock or lock even after being programmed, it's likely due to a faulty receiver module.

A dead 12 volt could also prevent your key fob from locking or unlocking. If the battery is faulty replace it with a new one that's the exact voltage and size as the original. It is also recommended to clean the battery's contact points with isopropyl alcohol or an equivalent electronic cleaner to avoid corrosion. If this doesn't fix the issue, it could be necessary to consult a professional.
