So, my Grandson has been faffing about for over a year, uming and arring over the cost of fixing his electric car key. He had the car for 2 years and wanted to sell to buy a different model so he was forced by circumstance to do something about it. He tried the dealer, too expensive and it was going to take too long. He tried ebay, good price but it was either going to take too long or would cost almost 7 times more to send it by first class post. I suggested we look at Amazon, we did and to our surprise, it was cheaper and would come by post in 24 hours, it did. The instructions were simple and replacement and assembly very quick, it was brilliant, worked a treat and more than value for the money. I fully endorse and recommend this product.
