You have inserted your ignition key into the lock, but it will not turn. Before you call a Professional Automotive Locksmith, there are several things to try. First make sure that it is not a locked steering wheel by turning the wheel from side to side while trying to gently turn the key. It may help to have someone else rock the steering wheel back and forth from left to right while you try to operate the lock.
If that does not work, insert some good solid silicone lubricant into the lock. WD40 will work in an emergency, but it has a solvent base and will dry the lock out after time. Do not use graphite unless you never wear clean clothes or keep your hands clean. I call graphite the black plague. After applying a generous amount of lubricant, insert the key and tap on it gently with the handle of a screwdriver. Caution must be used, especially if your key has a remote integrated into the head of it or a transponder inside.
If it is extremely cold, try blowing hot air into the lock with a hair dryer. You can also heat the tip of key with a lighter but be very careful not to touch the metal that you have just heated.
If none of the above works, it is time to call a professional automotive locksmith. If one is not available, you can have the car towed to a dealer or repair shop. If your car is a Ford, particularly a Focus, the lock has probably failed and needs replaced with one that will operate with your original key. If your vehicle was produced by Chrysler it may be possible to clean it after disassembling the lock, but I have found that this is a short-term cure and the problem will happen again. Replacement with a new lock is the proper solution. If you have a G.M.vehicle it may be possible to clean it out by flushing with a good cleaner, but replacement may be required if that does not work. Again, never replace a lock with one that does not operate with the original key. Most cars have transponders in the head of the key and reprogramming will be required. Your vehicle was designed to operate with only one key and that system should be maintained. Demand that your mechanic obtain a lock from a professional automotive locksmith or a new car dealer.
If you own a foreign vehicle produced by an Asian company like Honda or Toyota, demand that your lock be rebuilt by a professional automotive locksmith. Even if the lock must be replaced due to damage, demand that a professional automotive locksmith rekey the new lock to operate with the original lock.
Aftermarket locks sold by auto parts stores are generally not rekeyable nor of the same quality as the OEM lock. Sometimes they will carry locks produced by a OEM manufacturer, but they will need to be rekeyed. Dr Auto Lock only uses locks that are manufactured by the OEM supplier. Demand only the best parts be used in the repair of your vehicle. Inferior locks cost more in the long run and that is a fact.
Modern ignition locks have become more complex and this has led to increased failure occurrences. Ford Focus’s, Honda’s, Toyota’s, Chrysler and GM locks may experience failures due to many causes such as wear, poor design and small amounts of foreign debris being inadvertently inserted into the lock. Most failures result in the lock failing to operate with the proper key and require replacement or rebuilding.
Maintaining the use of the original key is extremely important. Most vehicles are now designed to use the same key for the ignition lock as well as other locks such as the trunk. When all keys are lost, a professional can obtain the original key code or use a door or trunk lock to generate a key. When locks using different keys are used to replace an existing ignition lock, a real problem is created, requiring the replacement of the lock when keys are lost. Locks that have failed should only be repaired by a professional automotive locksmith or a new car dealer that has the ability to code the new lock properly to match the original key. Many Asian auto makers only supply replacement locks that do not match the original keys. In this case it is very important to require the service provider have the new lock rekeyed to match the original key, by a competant automotive locksmith.
Most Honda, Toyota and other Asian vehicles are simpler to rebuild than replace do to the fact that easily rekeyed replacement locks are not available. Most Toyota failures occur from their use of split wafers, which I recommend be removed. Honda locks using a milled key instead of the older keys that can be cut on the same type of machine that cuts and duplicates common keys such as your house key, have split wafers that have been designed with a very fragile tip that is actuated by the key. These small tips, about the size of a large pin head can easily be broken off or deformed by a worn key or by forcing a key into a unlubricated lock.
Chrysler, Ford and G.M. locks that we use are produced by the same company that supplies the original manufacturer and we purchased them unkeyed so they can be matched to the original keys. Ford Focus locks had a severe design flaw and we replace those with a new lock utilizing a far stronger and reliable design. The same is true of some G.M. locks that were originally supplied by German or Asian companies, and they are replaced by an improved design lock.
Never use a replacement lock from an auto parts store. Only purchase a replacement lock from a professional automotive locksmith or new car dealer that can key the new lock to match the original key. I have encountered numerous aftermarket locks that have failed or the keys have been lost. Most of these locks are very inferior in material, design and security.
It is very important to use a professional automotive locksmith or new car dealer parts when replacing a lock. Not all locksmiths are competent to service vehicle locks. Vehicle locks and keys comprise the most complex devices that locksmiths service. Most commercial and residential locks are fairly easy to service but automotive lock servicing requires a very high knowledge of auto body service as well as steering column and interior panel removal. I have seen thousands of dollars in damage done by unskilled locksmiths and service techs that lacked the proper knowledge to service the locks.
