Attention for Doing all Key lost/programming New key on Ford

Today, I ' d like-to-share with notes-do-all key-Lost (program a new key) on Ford Focus. You know, Ford Focus from $ to, can is divided into and kinds, one with the Flat-type instrument Panel/dash Board And the other with a Bubble-bucket instrument panel. Security lights is in the middle of the instrument panel. In the case of the key all lost, program a new key first and does matching according to the instruction with 4d63 chip, by K EY programmer X100 or T300 (suggested by professional technicians), not needing password.

When doing all key lost, pay attention to the following matters:
1. Key chip problem
Choose the original 4d63 chip; Here, I mean, a fake one cannot do matching forever.

2. Insufficient battery voltage
To maintain the vehicle's battery power is sufficient, otherwise, there'll be matching unsuccessfully. (Communication failed)
Generally, go into the system 1 with X100 or T300; And it'll take your 8 minutes to does all key lost with free password. But no matter how long you wait for, you'll be prompted to wait for 8 minutes. The Electronic Control Unit (ECU) is located under the glove compartment in the front passenger side. When power was low, the ECU would make a strange noise, loud and creaky. In fact, just because of insufficient power supply voltage, ECU cannot don't work normally so, the relay inside produces This kind of noise when power supply voltage is insufficient. Press the horn with the hand; The sound was loud, but in fact, the voltage had been grossly inadequate.

3. Instrument panel malfunction
If the Focus is with the flat instrument panel, it's only takes a few minutes to doing all key lost by x-100, t300 key Programm Er. When your need to wait for 8 minutes of matching options, the instrument panel would become black for the security data is L ocated on it. It is normal. But if you need-to-wait for more than 8 minutes, or communication fails after waiting for 8 minutes, there is both Possibl E Solutions:
Solution 1:
Situation Description:
The vehicle has been in the status of key matching; One key has been programmed before and there are no another key to end of the program (even if the ignition is turned off).
Solution:
When we encounter such a situation, you need to reset the match between  ECU and security by the Auto key programmer x100; That's, re-match the ECU and security, about ten minutes needed. Here, you need insert a new key to finish the operation. After synchronization are complete, you does not need to match the key, and turn off and on with the key. This new key can is available for the car.

Solution 2:
Situation Description:
The car works well and it cannot start again when flameout for parking. 2 Reasons for this:
--reason 1
The instrument panel has been transfer for mileage correction. The chip is not a welded in a right-through;
--reason 2
The wiring is not fix. The security data is on the chip, the car connot start for poor connection.
Solution:
First, check if all links to the fuse have burned or not. If not, it's absolutely reliable method to go the 4S repair shop to deal with the problem:you can disconnect the car s B Attery for the minutes, then connect it. Start the car, security would be lifted.

Note:if your vehicle itself had an accident and cannot does all lost or add keys all the time (always communication failed) , try to disconnect the battery for a minutes to resolve. But, if the matching fails, you can start with the tango written if possible.

Ps:what should do when facing with one key only and no second end the programming?
Select "Remove all Keys" while all key lost. But the key inserted in the ignition lock would be preserved. This method was used only as a last resort.
