342.19 Perfection of security interests.
(1) Unless excepted by s. 342.02, a security interest in a vehicle of a type for which a certificate of title is required is not valid against creditors of the owner or subsequent transferees or secured parties of the vehicle unless perfected as provided in this chapter.
(2)
(a) Except as provided in sub. (2m), a security interest is perfected in one of the following ways:
1. If the secured party is an individual or a person exempted by rule under s. 342.245 (3), by the delivery to the department of the existing certificate of title, if any, an application for a certificate of title containing the name and address of the secured party, and the required fee.
2. Except as provided in s. 342.245 (3), if the secured party is not an individual, by the filing of a security interest statement containing the name and address of the secured party, and payment of the required fee, in the manner specified in s. 342.245 (1).
(b) A security interest is perfected as of the later of the following:
1. The time of delivery to the department of the certificate of title if perfection occurs under par. (a) 1. or of the application if perfection occurs under par. (a) 2.
2. The time of the attachment of the security interest.
(2m) If a secured party whose name and address is contained on the certificate of title for a vehicle acquires a new or additional security interest in the vehicle, such security interest is perfected at the time of its attachment under s. 409.203.
(3) An unperfected security interest is subordinate to the rights of persons described in ss. 409.317 and 409.323.
(4) The rules of priority stated in s. 409.322, the other sections therein referred to, and subch. III of ch. 409 shall, to the extent appropriate, apply to conflicting security interests in a vehicle of a type for which a certificate of title is required. A security interest perfected under this section is a security interest perfected otherwise than by filing for purposes of subch. III of ch. 409.
(5) The rules stated in subch. VI of ch. 409 governing the rights and duties of secured parties and debtors and the requirements for, and effect of, disposition of a vehicle by a secured party, upon default shall, to the extent appropriate, govern the rights of secured parties and owners with respect to security interests in vehicles perfected under this chapter.
(6) If a vehicle is subject to a security interest when brought into this state, s. 409.316 states the rules which apply to determine the validity and perfection of the security interest in this state.

Ch. 342, not ch. 409, governs the perfection of security interests in motor vehicles, but the creation of security interests is governed by ch. 409. Milwaukee Mack Sales v. First Wisconsin National Bank, 93 Wis. 2d 589, 287 N.W.2d 708 (1980).
Registration of goods under commercial law is conceptually distinct from registration of vehicles under vehicle registration laws. For a security interest perfected in another state to become unperfected, the requirement of “registration" in s. 409.103 (2) (b) requires both registration and issuance of a certificate of title.
