how can i get replacement keys for the mechanical key blades attched to the 2 remote control keys of my ford explorer 2014 model

My 2014 Honda Vezel shows a smart key system warning even though the key is within range
ANSWER : Hi, this problem appeared on 2013 Honda cars (Technical Support Bulletin 13-101), and may have been extended to 2014 models since the problem persists. If a problem code of B12D1 is also associated with this fault, the sub relay box (under the dash) must be replaced. It looks like your vehicle should still be under the Honda new car warranty. If so, check with your Honda service center about the TSB for this problem.

If you are not under warranty any longer, I would recommend having an inspection of your electrical components completed by a mobile, professional mechanic, such as one from YourMechanic, to diagnose this problem, get an accurate assessment of damage and cost estimate for repairs.

2008 Ford Edge turned key on key off key on and displayed check brake system and went off but able to replicate every time
ANSWER : At key on, many dash warning lights will come on momentarily, and then turn off, as a system test as well as bulb check. If the brake warning light goes off immediately, that is normal. If you suspect a fault though, a mechanic can be dispatched to perform a warning light diagnostic, which would include a check for any trouble codes that might have set. The mechanic would also check to see if the light perhaps refers to required maintenance involving the brake pads. Finally, inasmuch as you have referred to a brake system related warning light, one thing you can and should do is check the level of brake fluid to be sure it is above the minimum level in the reservoir. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

If remote key fob stops working, and you use the mechanical key to unlock your vehicle, why does the alarm still go off?
ANSWER : Hi There,
Generally, you should be able to unlock the vehicle manually with the key. As you know, the alarm will sound, however most vehicles will disarm the alarm when starting the vehicle within a certain number of seconds. I would suggest unlocking manually and then starting the vehicle with the key as quickly as possible, which should cause the computer to detect the key which will then disarm the alarm. Of course, you should then look to replace the key fob battery as soon as possible.

If I replace the ignition switch, can I use my existing BMW Keys with remote and valet key?
ANSWER : Yes, you can. The ignition switch is separate from the EWS system, so replacing the switch will still allow you to use the current keys you already have. Only if you have to replace a faulty key or EWS module will you have to possibly order all new keys.

One other possibility is there is an EWS issue where the key is not being properly identified not allowing the starting sequence. This would mean ordering an EWS module or keys from the dealer. Try out all keys you have to see if any will commence in the starting sequence. If none of the keys will start the vehicle, faults should be checked to ensure there are no EWS key identification faults. If no faults are present, then most likely the ignition switch is faulty. If there are key identification faults, then it’s either a key, module, or receiver that is the issue. You may want to consult with a mechanic who has the equipment to read out the Powertrain and EWS fault memories before replacing parts.

Anti theft system causing car not to start and mechanic can’t fix says take it to dealer but I don’t have a lot of money
ANSWER : Hi there:

In most cases if there is an issue with the security or anti-theft system on a vehicle that is causing the vehicle to not start it can only be repaired by the dealership for security purposes. However, it is possible that this mechanic misdiagnosed the problem; so you might want to have one of our mobile mechanics come to you and complete a car is not starting inspection; so they can inspect your GMC Yukon at your location and determine if these repairs can be made onsite.
