|If desired, you may use this list to significantly reduce the number of foreign auto keys to stock
since many keys are the same except for the bow. In some instances the substitute directly
following the blank number must be used because of a longer neck or other differences.
other cases, many blanks may be interchangeable and the recommended substitution is just a
matter of preference.
Keys that you don't need to stock are marked with an asterisk (*), even though you may wish to with some keys. Many of these keys are not very common and you may wish to purchase small quantities.
It should be noted that not all foreign keys have an "X" designation. There are many keys with other than "X" designations which have interchangeable substitutes.

---- NOTES -----
Old Datsun and Nissan. X114 may be used for all the old Datsun X7 applications. When introduced in '81, the X114 became the master and X7 remained as a valet key. X114 will enter all the earlier locks. The same may is true for the reverse keyways used on Subaru and some Datsuns (X115 and X6). Do not use or confuse X6 with X210, etc. They are different.
Mazda 10-cut. X222 has wider center grooving than X188, however X188 may be used for X201, X221, X222, X244 and X249 Mazda/Ford applications. These are all the same bitting specification and code series. The X244 and X249 do not have the center millings and therefore much stronger and better to use where possible, such as 1997+ Escort, Protege, etc.
Mazda 7-cut. The Ford Capri from about '91 on uses the Mazda 7-cut key and will not allow blanks such as the X178 etc. to enter the ignition all the way because of the widened portion of the blade near the bow. These ignitions may be identified by ears similar to typical domestic Ford locks. You can use the Ilco X202 in these because it does not have this widened portion, or you may easily trim down the widened portion on the other blanks. Even though I listed the X202 as preference because it will work all the applications, I actually use a modified X178 because it looks better.
Hyundai. Keys such as X236 etc. are very similar to the X176 etc., and may be mistaken as interchangeable. There are two differences. The keys are slightly different milling geometry leaving a thicker blade with other differences in the profile, and the bitting specification uses a smaller increment leaving more metal on a deep cut. The same is true of the reverse keyways X232 etc. and X174 etc.
Isuzu Truck. The large diesel trucks from 1986 and up use X158 which has a precut tip not found on the original keys. It is also slightly longer than the original keys and can be trimmed easily. It is important to note the shoulders are too wide to enter the door locks and must be trimmed slightly. The later trucks use the same blade, but with a much longer neck. As far as I know, there are no replacement blanks available for the later key. You can use the X245 which is really the same bitting specifications, and uses the "N" code series for this key is the same as one of the code series' used for the X245 application. You may also grind back the bow on the X158 for later trucks, but it looks horrible.
VW and Audi. X88 will work for X9, X139 and X203 applications with exception the bow will stop against the dash on some later model Audi's preventing full insertion. X139 and X203 are slightly stronger keys. You may also use X9 for all, if it is the later version (milling changed in early 80's). Many late model Audis have transponder antenna coils attached to the ignition, but the equipment is not active. This adds dimension to the front of the lock, which may require you to trim back the bow on some keys to operate properly.
Suzuki, Kawasaki and Yamaha. The relationship of a few of these key series would suggest some are the same lock manufacturer. One of the old Suzuki and Yamaha series in the 1980's used a group of six keyways. The first character of the code was a letter (A to F) which specifies the keyway, followed by five numbers which are either a reverse direct digit code, or a conversion code. At the time, Taylor produced four blanks (X117 thru X120) to use for these six key series. The X117 was milled to enter both the C and E series, and the X118 was milled to enter the D and F series. Ilco still makes the X117 and X118 but the catalog illustrations suggest they are not composite milled anymore. There is some confusion here because blanks I have purchased very recently are milled to pass two keyways each, unlike the catalog illustrations. They now also make two keys specific for the other two keyways (YH50 and YH51) which completes the group of six.
The five latest Kawasaki keys X258 thru X262 appear to be the same keyways as five of the original six keyways used for Suzuki and Yamaha. Both the Yamaha/Suzuki and the newer Kawasaki use a letter to indicate the blank, and the Kawasaki series is followed by the actual cuts in reverse order just like the old series'. Other than different keyway letter designations, this series uses six cuts instead of five. The older keys have a longer neck, so it would be possible to file the shoulders back one space and use the older keys for the X258 thru X262.
Additionally, the four additional Kawasaki ATV keys (X254 thru X257) are the same keyways as the old X117 thru X120, and the old blanks may be used for the newer application. The bitting specifications for all these keys are identical (4-depth system). Earlier Yamaha keys (X62, X63 etc.) use the same spacing, but a 3-depth system with a greater increment.
Kawasaki "Z" series keys. The X103 has been used since the 1979 on certain Kawasaki motorcycles, and the applicable code series is Z5001-6000. In 1999, a new ignition lock appeared labeled KM-8, and it also uses the Z codes but requires a key with a longer neck. The newer X266 is a longer version of the X103, but it will not work for the new locks because the neck is too short. Additionally, the X266 will not operate all the locks on a bike which would use the X103, because the thickness of the shoulder stops are the same thickness as the blank, unlike the X103 which has the stops thinned. The only known replacement blank for the KM-8 ignition is the Silca KW16CP which is steel. This is somewhat obscure in this country, but one source is Blue Dog Keys.
Kawasaki X105 and X106 keys. These were originally for the A and B direct digit code series. The current version of these two keys are milled different than the old Taylor versions. The difference is the center web, which is thinner on the old version. Use the newer KW14 and KW14R blanks which are milled like the old X105 and X106.
Honda X42 and X43 keys. The current versions of these two keys are very different from the original Taylor blanks, and they will not enter locks of the old intended applications. It appears you can use HD65, HD66, HD67 and HD68 as replacements where needed.
