Lost keys, replacement key not working?

I bought this key PT Auto Warehouse ILC-279L - Ignition Lock Cylinder with Keys (Replaces # 5S4Z-11582BB in Amazon and bought chip 4D 60 glass to insert into it. The key was programmed. The car couldn't start. I don't know where the problem lies. If I turn on the ignition, the hazard light continues blinking. I feel the PCM has not recognized the key or there is error in the programming. After the programming didn't work, I contacted another locksmith who said the Datalink port failed to recognize the scanner. The key need to be programmed through fibre. All these failed. The car hasn't started yet. I tried to contact another seller to get new key if the key is the problem, he requested for the key number and the chip number. Can you provide that? Do you think the key is the problem? When the key is turned on, the crankshaft rotates but the injectors are not functioning. What's the solution?

The security light is flashing when I try to crank the engine. If I want to get aother key together with the scanner, which should I go for. This is my VIN 1FAFP33P32W318992. Repair manual suggested strattec, rotunda and the likes. My mechanic said product doesn't matter and what is most important is the chip. Online merchant is requesting for key number and chip number. Why I want to order both together is to avoid further delay in shipping if the problem happens to be the key after diagnosing since item is shipping to Nigeria which will take average of three weeks. This I found https://store.carkeysexpress.com/keys-and-remotes/Ford/Focus/2002. Don't know if it will be a match or the one at hand is okay but I want to save time and be efficient. Thank you so much for your contributions. Much appreciated

This is the https://www.carandtruckremotes.com/fordkb37.html one I came across. Thanks

Good day, I just took delivery of the scanner now. Is there any prior I need to know before I start scanning? Can I also use it to detect if the key is working or not? Any special directives? Thanks

Good morning, I plugged the device but it reads ' failed to connect' 'link error'. What should I do?

The scanner reads ISO 1411 -2, KWP 2000, SAE. In the end, it showed 'failed to connect ' linking error. What does it mean, what should I do? Thanks

Maybe because I have not registered the scanner. I am contacting the support team but there has been no positive response yet. I need to scan QR code before I register. I don't see I can scan QR code. I continue with the registration but I failed to submit.

Registration could not complete.

The autel scanner was tried on another vehicle. It was communicating but it didn't read any codes. The menu displayed. What I have realized is, I might right or wrong but the most important thing right now is how to ensure that data link communicator DLC is communicating with the PCM. If that is not in place, I wonder how the previous mechanic was able to program the key he claimed he had programmed. From the software manual I have, it states that ' the ISO 9141 communication network will not function if the wire is shorted to the ground or battery voltage. Also, if one of the modules on the ISO 9141 communications network loses power or shorts internally, communication to that module will fail. I am suspicious of the starter relay K22 C1017 in the CJB. How do I test relays. Do you think it is internal short that has made the DLC not to communicate. If the DLC is communicating, then the key can be programmed and the car get running. You can review this and state your opinion. I am glad you help. Thanks

There are no changes to it to the best of my observation. It just continues blinking (before and after turning on the ignition).

After the ignition on and off, the car chime. The car also has active security installed which the mechanic disconnected during the time the car was experiencing the battery draining.

At the last moment when this present key was programmed, the wipers were working. Presently, they are not working.

The car has never started since I lost the keys. The security light has never stopped too.

Good morning, can you recommend a voltmeter for purchase.
